Approval of Final Score

[OKREF]

In the OP, the officials checked with the table both books matched and the scoreboard reflected what the books said. When the horn sounded and ended the game the officials looked at the table and nobody said anything. Once they leave the visual confines of the floor the score was 60-59 visitors. Then it says they were leaving the gym and were told the home book was wrong. There is nothing that can be done at this point. Whose to say it didn't get changed after the game was over?
