Free throw, with a player fouling out

[gwockenfuss]

I was watching a 8th grade game last week, and this situation happended.

Player A, was fouled by player B, (which resulted in player B's 5th foul. the ref's lined up the players for player A to shoot the 1-1. No-one from the scorer's table notified the refs that it was player B's 5th foul. They went ahead and shot the first half of the 1-1. Player A made the shot. The ref gave the ball to player A again for the second part of the 1-1, when the coach was yelling that his kid has fouled out, and he needed a sub. (The scorer finally realized the kids had 5 fouls). The Player A made the second shot. The ref's came over to the bench and the scorer told the ref's that Player B had 5 fouls. One ref said they redo the 1-1 with a correctable error procedure, the other agreed, The play stood as is. The coach of Team B got his sub in for the Player B who fouled out. The opposing coach team A wanted a Technical, on Team B for having an illegal player on the court at the time of the free throws. Team B coach then wanted a Time-out, which was granted. The refs gave the ball to Team B under the basket with the run of the baseline due to the 2nd basket being made.
How would you handled this situtation?
