No need to special-case 2.14.2 while using
(add-score parser (scorify-music ...
#(cond ((member (lilypond-version) '("2.14.2" "2.16.2" "2.18.2"))
(add-score parser (scorify-music the-test-music parser)))
((string-ci<=? (lilypond-version) "2.19.32")
(add-score (scorify-music the-test-music)))
(else (ly:error "unknown version: ~a" (lilypond-version))))
