Administrative T or bookkeeping error?

[Back In The Saddle]

A couple of minutes into the first quarter of a JVB game the H bookkeeper calls me over and tells me they have a wrong number in the book and that she knows we'll need to assess a T for this. We assess an administrative T. Coach is okay with it. Game goes on.

Later in the day I got thinking more about the situation. Though it didn't occur to me at the time, I know that the bookkeeper copied the lineup directly from the previous page of the scorebook. Assuming that the number was correct on the previous game's lineup, would this be classified as a bookkeeping mistake rather than an incorrect number? It seems to be pretty much exactly as if the coach handed the scorekeeper a correct written lineup, but the scorekeeper entered it incorrectly into the book.
