If you look at the definition of `bookpart-score-handler' in my
file, you see that the book-part argument is not used. Instead,
all scores are added to the toplevel-scores parser variable (even
though they are not really toplevel, it does not matter).
The `toplevel-bookpart-handler' then uses this variable to actually
add the scores to the bookpart. This function is called by the parser
when a \bookpart block is closed, so at this point the bookpart object
is known.

You can change the book-score-handler and toplevel-book-handler to
act the same way.

Do you also create books on the fly?
