Interesting Situation

[PIAA REF]

This situation was brought up at my last meeting. Girls varsity game, 3 man crew.
A1 shoots the ball beyond the 3 point arch, Trail has a foul call on the shot on B1. At almost the same time (maybe a hundreth of a second later) The lead official has a push on A2. The shot misses. They decided that since the first foul was first that the second foul should be ignored. I disagree. I believe that the correct way to do this is count both fouls, A1 shoots 3 free throws with the lane cleared. Then B3 would either shoot free thows if their team was in the bonus or B would have the ball for a spot throw-in out of bounds where the foul occurred. (order of what was called)

Let me know if I was correct.
