Sorting order for each individual Portfolio item

Hey guys,
I am revisiting this for a 2nd time because the original attempt isn’t working very well.
This is a very high maintenance client, so this needs to be working correctly.
For each portfolio item, they need to be sorted in a specific order. There are several galleries, and within each gallery are sweveral items.
For every gallery item, each item needs to be in a specific order. How can I obtain this? The post-type-order plugin jumbles everything up. I tried taht several times with no luck. What other solutions can you offer?

What I originally did was added this within the functions file to help define order:

/*
* portfolio sort order
*/
add_filter(‘avia_masonry_entries_query’, ‘avia_random_image_query’, 10, 2);
function avia_random_image_query($query, $params)
{
if(empty($query[‘post_mime_type’]))
{
$query[‘orderby’] = “menu_order”;
$query[‘order’] = ‘ASC’;
}

return $query;
}

It’s not responding like it should where each item within each gallery is order in a specific way.
Thanks!
