There is a small bug here...

You use code to insert in template "USERCP_SHELL"

<!-- PM Search -->
<if condition="$show['pm_search']">
  <tr class="alt2">
    <td class="$navclass[pm_search]" nowrap="nowrap"><a class="smallfont" href="private.php?$session[sessionurl]pmsearch=1">$vbphrase[search]</a></td>
  </tr>
</if>
<!-- /PM Search -->

Then, if you go to to USERCP and look into HTML source code you will see that:
class="" is empry there.

	<!-- PM Search -->
		<tr class="alt2">
			<td class="" nowrap="nowrap"><a class="smallfont" href="private.php?pmsearch=1">Поиск</a></td>
		</tr>
	<!-- /PM Search -->

Now I understand why you use <tr class="alt2">, but it not the right sollution here...

But <tr class="alt2"> and <td class="alt2"> are the different things!
The cell "Search" will look differently if you use some custom style.

The quickest way to fix this one is to replace the code with this one:

	<!-- PM Search -->
	<if condition="$show['pm_search']">
		<tr>
			<td <if condition="$navclass['pm_search']">class="$navclass[pm_search]"<else />class="alt2"</if> nowrap="nowrap"><a class="smallfont" href="private.php?$session[sessionurl]pmsearch=1">$vbphrase[search]</a></td>
		</tr>
	</if>
	<!-- /PM Search -->

As you see I added a condition:

<if condition="$navclass['pm_search']">class="$navclass[pm_search]"<else />class="alt2"</if>

And we don't need any hooks to call here
