Add sort to product tag search

[nbarnum 0]

I'd like to add sorting and pagination to the tag page (example.com/search?tag=blouse). The product-sort.tpl will not show unless the $orderby and $orderway are set.

 

On line 770 of classes/Search.php it states:

public static function searchTag
($id_lang, $tag, $count = false, $pageNumber = 0, $pageSize = 10, 
$orderBy = false, $orderWay = false, $useCookie = true, Context $context = null)

When I changed the $orderWay and $orderBy nothing happened.  Any suggestions?
