 It's not the instruments being listed, it is the parts which are being listed.  Parts are titles and therefore, should be capitalized.  As far as it being "just plain wrong", any book of style will tell you proper titles are always capitalized and I don't see grammatical styling as a moral issue.  The same applies to the use of the ampersand (that's the fancy word for the symbol that replaces the word 'and' which apparently you did not know).  Somehow, I don't believe you are a doctoral student or professor of music or grammar; the person I'm consulting for this post is a graduate student in music performance who owns the scores for 1948 and the 1984 editions.  Please stop posting this incorrectly.
