Rules Interp. Question

[PIAA REF]

We had a crew that had the following situation. They had an overtime game. The jumpers lined up for the jump ball incorrectly. Team A won the jump and scored on the first possession. As soon as they scored (Before B inbounded) one of the refs realized they jumped incorrectly and sounded his whistle. OK I understand the ruling although they messed it up as they awarded B 2 points and A the ball out of bounds, no clue how they forgot the rule. Anyway. My question and discussion with other officials is where to put the ball into play after you turn the teams around so they are going the right direction. The rule book says to resume play with throw-in at POI. The POI was a made bucket by A. I said that I would have took the ball to the other end of the court (a's correct basket) and allowed B to run the endline. Others said they would have kept it in B's frontcourt and just administered a spot throw-in. Which do you think would be correct.
