It sounds like you're talking about kids playing in a competition. Parents, coaches and all the other adults involved in minor-games shall always give the good, honest example!
As the umpire you have to rely on that. I would, in this case, call both coaches together and explain that Homebook can't be trusted. Therfore home-scorer is to be thanked (for nothing) and be excused (= leaving dug-out!!!). Scorebook that can be trusted now is official... Play on.
Home coach is having problems with that? Call it a game; if a team won't play fair, we aren't playing at all!
Make sure you collect all the needed papers, i.e. scorebook sheet from both teams. No one can complain about you at the league director. You did what had to be done. Show the books at the director, he will forfait the visiting team...

You seem to have made the assumption that the scorekeeper was trying to pull one over on everyone. If I wrote it that way, my apologies. I have no reason to believe this was intentional. I truly believe she was just confused and disorganized. Additionally, this book was in the stands, not the dugout.
