Here's the answer I received from Hank Zaborniak. He's been the Assistant Commissioner of the Ohio High School Athletic Association for 6 years, and I sent his "committee" an e-mail asking for help. Hank Replies:
"Based on the info you've provided, it appears to be a simple correctable error and the team A would win 55-54."
Unfortunately, he didn't explain his reasoning or give a rule reference, but he's in a position to know (I assume) what the right call should be. Comments?
