If there truly was a mistake and you find it out, correct the mistake and move on. This really is not that hard to do. Let the player play if it is clear this was a mistake and continue the game. Then if the coach has anything to say, I would say, "Well you should be keeping track and making us aware if there was a discrepancy."

Otherwise you are at the mercy of the scorekeeper and the teams to point out something is wrong. Otherwise you assume and safe to do so that everything is correct.
