I have that textfield set to "cart", and it redirects properly to my cart when I add a product. It's worked in every version of UC I've used, from alpha 8 on up. I currently use beta 5. Perhaps you have a URL alias for the cart which is screwing things up?
Hmm, good to know it works. I think it might be one of the other modules I have installed (maybe uc_aac) because I know some of them hook into the add_to_cart function and perhaps end up disabling that feature. I'll have to poke around some more.
