Well spotted. The embarrassing thing is that we even get there: this is something that should rather be caught earlier. We have key = #(define-music-function (tonic pitch-alist) ((ly:pitch? '()) (list? '())) [...] and the word major qualifies as list? by getting converted to '(major) which is a symbol list like needed for some override/tweak specifications. So it very much looks like we should use a more specific predicate than list? for the scale type in order to not have that user error pass down in this manner.
