So, SAC never answered my three emails/inquiries. No matter what ends up happening here, I will stand firm in my resolve never to order from them again. Terrible customer service: bzzzzt, goodbye!

But, I did call backcountry.com's customer service today at last and (very politely) spoke to a decent guy, Matt. Although he didn't apologize for what had happened, he immediately took action by putting in a tracer in on my package to UPS. At home tonight I got a call from a very friendly UPS rep in Salt Lake City. She apologized several times for the mix-up and was able to confirm that my package did indeed go to my 6.5 year ago address in Cary, NC. She was also able, at my request, to put my new address into their system so there would no longer be an association between my PO box and my old address (how that association ever was made, I don't know, but I suppose we got our PO box shortly before moving).

The next step is for UPS to contact the folks who live in our old house now to attempt to retrieve my jersey and redeliver it to my current address. The thing I wonder is, why didn't they contact UPS already to report a misdelivery? They've had the package since 9/27, over a week. I would certainly have done that if I'd received a package with someone else's name that I had not ordered!

So, we shall see if it turns up, and if not, what the next step is. Hopefully it will all work out. Perhaps I'll see that jersey yet (but whether it will fit me or not is another matter entirely!)
