I had a functionality requirement similiar to btappan's, but I needed the custom field to only be visible to those users who had permissions to view private custom fields.

To accomplish this, I modified KirbyDE's hack. I'm reposting Kirby's hack with my modifications (I hope this is proper procedure - this is the first time I've posted code) - thanks KirbyDE!!

The following steps will set up your Member List to display the Company Name (user field 5 in this example) as the first column and sort by it if the user has permissions to see private custom fields (assuming that user field 5 is a private custom field of course ), and display the default Member List if the user does not have permissions to see private custom fields.

In memberlist.php FIND

PHP Code:

// set defaults and sensible values 

if ($sortfield == '') 
{ 
        $sortfield = 'username'; 
} 


REPLACE that WITH

PHP Code:

// set defaults and sensible values

if ($sortfield == '')
{
    if ($permissions['genericpermissions'] & CANSEEHIDDENCUSTOMFIELDS)
    {
        $sortfield = 'companyname';
    }
    else
    {
        $sortfield = 'username';
    }
} 


then FIND

PHP Code:

switch ($sortfield) 
{ 
         case 'username': 
                 $sqlsort = 'user.username'; 
                 break; 


BELOW that ADD

PHP Code:

case 'companyname': 
                 $sqlsort = 'userfield.field5'; 
                 break; 


Revert to the original versions of your memberlist and memberlist_resultsbit templates.

Set your Company Name field to NOT show up on members list

In template memberlist FIND

<td class="thead" align="$stylevar[left]" nowrap="nowrap"><a href="$sorturl&amp;order=ASC&amp;sort=username&amp;pp=$perpage&amp;ltr=$  ltr$usergrouplink">$vbphrase[username]</a> $sortarrow[username]</td>

ABOVE that ADD

<if condition="$permissions['genericpermissions'] & CANSEEHIDDENCUSTOMFIELDS">
<td class="thead" align="$stylevar[left]" nowrap="nowrap"><a href="$sorturl&amp;order=ASC&amp;sort=companyname&amp;pp=$perpage&amp;ltr=$ltr$usergrouplink">Company Name</a> $sortarrow[companyname]
</td></if>

In template memberlist_resultsbit FIND

<td class="alt1Active" align="$stylevar[left]" id="u$userinfo[userid]">
		<a href="member.php?$session[sessionurl]u=$userinfo[userid]">$userinfo[musername]</a>
		<if condition="$show['usertitlecol']"><div class="smallfont">$userinfo[usertitle]</div></if>
	</td>

ABOVE that ADD

<if condition="$permissions['genericpermissions'] & CANSEEHIDDENCUSTOMFIELDS">
<td class="alt2Active" align="$stylevar[left]"> $userinfo[field5]
</td></if>

EDIT:
The following will allow the alpha search at the top of the memberlist page to sort by the added userfield.
In memberlist.php FIND

PHP Code:

    if ($ltr != '')
    {
        if ($ltr == '#')
        {
            $condition = "username NOT REGEXP(\"^[a-zA-Z]\")";
        }
        else
        {
            $ltr = chr(intval(ord($ltr)));
            $condition = 'username LIKE("' . addslashes_like($ltr) . '%")';
        }
    } 


REPLACE that WITH

PHP Code:

    if ($ltr != '')
    {
        if ($ltr == '#')
        {
            if (($sortfield == 'companyname') OR ($sortfield != 'username' AND ($permissions['genericpermissions'] & CANSEEHIDDENCUSTOMFIELDS))) 
            {
                $condition = "field5 NOT REGEXP(\"^[a-zA-Z]\")";
            }
            else
            {
                $condition = "username NOT REGEXP(\"^[a-zA-Z]\")";
            }
        }
        else
        {
            $ltr = chr(intval(ord($ltr)));

            if (($sortfield == 'companyname') OR ($sortfield != 'username' AND ($permissions['genericpermissions'] & CANSEEHIDDENCUSTOMFIELDS))) 
            {
                $condition = 'field5 LIKE("' . addslashes_like($ltr) . '%")';
            }
            else
            {    
                $condition = 'username LIKE("' . addslashes_like($ltr) . '%")';
            }
        }
    }
