Strange SERP result on Google

Our site got majorly downgraded by Google yesterday. I hope this is
just an isolated incident. Just wondering if anyone else out there has
experienced something like this.

If you search "bargaintix" on google (the name of our company), our
site (page rank 5) comes in 10th. A site whose name is mispelled
"bargintix.com" (page rank 2) comes in first.

This makes no sense from a programming perspective, and seem only
logical if there's some sort of human interaction going on here. Any
ideas?
