I am curious then why does this cart look different than every other Pitstop cart that I have searched for?
Game publishers often switched suppliers back then, mostly for cost reasons. I can think of several A8 titles by several companies that have two or more completely different cart variations (Congo Bongo by Sega comes to mind). I don't know much about Epyx specifically, and I don't collect Atari 8-bit software extensively, so I don't have a clear answer in your case. I've never seen a copy of Pitstop like that either, but that doesn't mean much.
I can tell you, as I mentioned earlier, that a few companies used DEICO as a supplier. I have a few Sierra On-Line cartridges that look exactly like yours (DEICO board and shell, square label pasted on the back of the cart), and at least of one of them came from a sealed retail box.
Beyond that, I have rarely seen a prototype that had dot-matrix printed labels on the EPROMs (they're always hand-written). From what I can see, your cartridge also appears to be the final version, not any kind of beta. You may have an uncommon variation, but it's not a proto.
