Teams pointed the wrong way.

I'm at work and don't have a rulebook handy, so I'll solicit input. This play happened in a play-off game (ugh), and I got it from an official-friend of mine who was on the clock for the game.

Teams are pointed the wrong way to start the game. Team A wins the tip and hits a three-point shot on the first possession. Clock-keeper realizes what's happened and sounds the horn and beckons the referee to the table.

The referee wiped the three, awarded team B two points (reasoning being that a team can't score three points in the wrong basket), then gave team A the ball going in the correct direction.

1) What should have been done?

2) What should have been done if nobody had noticed until the score was 8-7?
