What to do here? Small pair late in the tournament.

I'm in 4th in chips, when I get pocket 3's two off the button. I do my standard open raise to 3x, and am played back into with a minimum raise (400 to call, already have 600 out there). I call just hoping to get a set for cheap. He bets out the minimum on the flop. This could mean he just has overcards (perhaps AK) and missed. What do you do? I had about 1300 left (about 6 1/2 BB) and I've put just under half my stack into the pot already.
