Old thread, I know. I've updated Andreas' plugin to account for forum display order as well as alphabetical ordering:

PHP Code:

$forumcheck = end($vbulletin->forumcache);
if (!$forumcheck['sorted'])
{
    function forumsort($forum1, $forum2)
    {
        if ($forum1['displayorder'] == $forum2['displayorder'])
        {
            return strnatcasecmp($forum1['title_clean'], $forum2['title_clean']);
        }
        return ($forum1['displayorder'] < $forum2['displayorder'])
        ?    -1
        :    1;
    }
    uasort($vbulletin->forumcache, 'forumsort');
    $lastforum = end($vbulletin->forumcache);
    $vbulletin->forumcache["$lastforum[forumid]"]['sorted'] = 1;
    build_datastore('forumcache', serialize($vbulletin->forumcache));
} 


Works on my 350+ subforums. I only wish vB could leave the database do this simple job. Enjoy!
