Incidentally, I found I could simplify these with "filter":
(define musical-column-grobs
(map car
(filter (lambda (a) (not (ly:assoc-get 'non-musical (cdr a))))
all-grob-descriptions)))
(define non-musical-column-grobs
(map car
(filter (lambda (a) (ly:assoc-get 'non-musical (cdr a)))
all-grob-descriptions)))
