If you define the function with define-scheme-function instead of
#(define ...), why not call it as

new-score = \make-rehearsal \choirScore

?  That's just a detail.  The main problem is that ly:make-score is an
internal function that does not do the full required job of creating a
score from unprepared music.

To get the full preparation necessary, use scorify-music instead of
ly:make-music .  It uses ly:make-music internally but does other
required things.
