Comment (by MarcGuay):

 Here's a proposed solution:

 {{{
         if ( $child_of || $hierarchical ) {

                 // Get new collection of all post_types queried for
                 $all_pages = get_posts(array('post_type' =>
 $r['post_type']));

                 // Get children based on child_of parameter
                 $_pages = get_page_children($child_of, $all_pages);

                 // And remove elements which were not in the $pages
 collection queried above
                 foreach ($_pages as $key=>$value){
                         if (!in_array($value,$pages)){
                                 unset($_pages[$key]);
                         }
                 }
                 $pages = $_pages;
         }
 }}}
