Need function in cart "sort products by category"

[eqdb]

I am using VM as a directory for film gear. Users are able to create "loading lists" (= cart) with it.

Given:
VM: 2.6.14
J: 2.5.28
PHP: 5.3.29
Live URL: http://eqdb.bvb-verband.com/en/

My question:
I would like to change the sort order in cart by category.
Any idea how to do this?

What I have done so far:
I was able to implement the category in the cart within the file "template/horme2/html/com_virtuemart/cart/default_pricelist.php"

Any help is appreciated.
