i had the same problem the last hack i built, but i managed to solve it finally. here's my code:

PHP Code:

$vbulletin->input->clean_array_gpc('r', array(
    'userid'    => TYPE_STR,
    'act'    => TYPE_STR,
));

$vbulletin->GPC['userid'] = intval($vbulletin->GPC['userid']);
$vbulletin->GPC['act'] = intval($vbulletin->GPC['act']); 


and now it should work, i used type_str for the id cause that's the only one that worked...
i hope it will also work for you and you won't have a problem. all you have to do now is the "if" part.
