Official scorer

This happened to me about 3 years ago in a varsity girls game.The kid that was handling book for the host school couldn't have been more than 8 years old.When I saw that I asked the officials if it was okay if I could be the official book for this game and they said ok.As a courtesy I went and told the host coach about the officials redesignating me as official book.
I went just out of curiosity and looked at his book at the break.The kid knew his stuff but if something went wrong in that game I wanted the heat to be on me instead of the kid.How often do you see schools who put young kids like this in that position and what as associations do you do about it other than redesignating the visitor book as official?
