I can't claim any expertise here. In C you would just force the case
(tolower say) and then just test for that. 
However, I have had a thought that would make these sorts of scripts
easier to write:
I propose we could have a

(d-FindDirective-standalone tag)

which would move the cursor to a standalone directive with the named
tag. (Variants for forward/backward and chord/note/staff directives).

The idea is that you could put a markers in the music and be able to
find them again, rather than trying to keep track of the cursor (which
can be tricky in Denemo because of its concept of an appending postion -
cursor stopping on the barline). Specifically the ReadingNoteNames works
by putting up notes & then changing their noteheads - relying on
tracking where the cursor is. Instead the note could have a directive
attached marking it as the note prompted for, and then the note can be
found again even if the user has moved the cursor meanwhile.

I think the infrastructure may all be in already - I recall writing
stuff for doing named bookmarks using the old LilyPond inserts. So this
is largely cosmetic: in particular we could now have a command

(d-PutDirective-standalone tag)

which would put a directive without setting any fields, which is what
you would do to place a named marker to mark a spot in the music, but
without it having any effect on the print out or the midi out or even
the display.
As a bonus, the existence of such a command makes it easier to explain
DenemoDirectives - at the moment creating a DenemoDirective is a
side-effect of setting a field - e.g.
(d-PutDirective-standalone-display "mytag" "hello")
creates a directive and sets the display field.
Now we can describe this as

(d-PutDirective-standalone "mytag");;; create a standalone directive
(d-PutDirective-standalone-display "mytag" "hello");;; set its display field

although in practice we would omit the first line.
