Could you please implement a sortorder parameter for the CART_ITEMS function. To allow you to sort by line item putting the latest items added to cart at the top of the list.

A lot of ecommerce site are now doing this, including Amazon. When you add an item to cart they show the latest added item at the top instead of the bottom of the list.
Having products shown at the top of the list is helpful when you have a lot of items in your cart so you don't have to scroll all the way to the bottom.
