what about the sort value?

You know , when you're in Admin mode and you click on your catalog, then you see the following column headers..

ID
Categories / Products
Model
Price/Special/Sale
Quantity
Status
Sort
Action


I thought that the "sort" value would override the 1a 2a 3a 4a, does anyone know what that is used for?

Do you think my cart might not be functioning correctly because of the "Column Layout Grid for Product Listing for 1.3.8 contribution"

I tried turning it off, but it does not seem to make a difference with my sort order..
