I am not sure. You may try to replace that part of the code, with :

PHP Code:

function print_template_javascript()
{
    global $stylevar, $vbphrase, $vboptions;

    print_phrase_ref_popup_javascript();

    echo '<script type="text/javascript" src="../clientscript/vbulletin_templatemgr.js"></script>';

    print_label_row(iif(is_browser('ie') OR is_browser('mozilla', '20040707') OR is_browser('opera'), $vbphrase['search_in_template'], $vbphrase['additional_functions']), iif(is_browser('ie') OR is_browser('mozilla', '1.7'), '
    <input type="text" class="bginput" name="string" accesskey="t" value="' . htmlspecialchars_uni($GLOBALS['searchstring']) . '" size="20" onChange="n=0;" tabindex="1" /> 


And see if it is working. If not, you may also try copying the clientscript/vbulletin_templatemgr.js file from vb 3.5 to your server and see if it will work.

I have absolutely no idea about Opera.
