To be honest, I really don't know how to do what you want. I found these lines in profile.php:

PHP Code:

    // options bitfield
    foreach ($vbulletin->bf_misc_useroptions AS $key => $val)
    {
        if (isset($vbulletin->GPC['options']["$key"]) OR isset($vbulletin->GPC['set_options']["$key"]))
        {
            $value = $vbulletin->GPC['options']["$key"];
            $userdata->set_bitfield('options', $key, $value);
        }
    } 


So, perhaps they are worth looking into. And then in includes/functions.php are these lines:

PHP Code:

// decipher 'options' bitfield
    $user['options'] = intval($user['options']);

foreach ($vbulletin->bf_misc_useroptions AS $optionname => $optionval)
    {
        $user["$optionname"] = ($user['options'] & $optionval ? 1 : 0);
        //DEVDEBUG("$optionname = $user[$optionname]");
    } 


I think you're just gonna have to play with what you find.
