Simultaneous Foul?

[bigdogrunnin]

Had a situation occur yesterday in a tournament, want to know if it was handled correctly.

5.44 seconds left in game. Team A is ahead by 4 points, and will gain possession of the ball OOB because of a common foul by Team B. I am "T," my partner is "L" (2-person crew). I hand the ball to white OOB for the throw-in, and begin my count. As I get to 3 of my 5-second count, I have a foul by Team B right in front of me. At the exact same time, my partner has a foul by Team A about 30 feet down the floor. We call simultaneous fouls, report each foul to the scorer, and put the ball back at the POI - Team A throw-in. Is this correct, and can someone please provide a reference in the NFHS rules and casebook. Thanks.
