Interesting.  Looks like books/bookparts as scheme function values are
not handled in the parser.  Probably worth a bug report.

In the mean time, you could define a void function and let it just call
toplevel-score-handler on your scores.  Of course, this would no longer
allow you to place those scores in a book or bookpart.
