Illegal, unsportsmanlike substitution.

I witnessed this at a middle school game last night. I was sitting in the stands with no game responsibilities.

Near the end of the game. Team B (visitors) is leading by 3. Player on team B (#44) is fouled and is shooting 2 shots. First inept looking shot misses badly. Team B calls full time out. After the time out a different player (# 42) goes to the line and strokes in second free throw. Referees do not notice any of this.

I only umpire baseball so my knowledge of basketball is somewhat limited but I assume that it is one or both referees responsibility to catch this infraction and penalize accordingly.

My question is if I were the official scorer (a task which I do from time to time) and I notice a case like this which goes unnoticed by the officials, can or should I bring it to the attention of the officials and if so, when?

Also just out of curiosity, what would the imposed penalties be in this case?
