I don't know.  If you want to try to debug the problem, I'll be happy to
give you some ideas about where to start.  But I don't have the time to work
on this right now. 

You can use different music for the notes than for the tablature.  I realize
that this is not desirable, but it's one way around the problem.

You might also try redefining SEMI-SHARP.  Look at scm/lily-library.scm, and
find

(define-safe-public SEMI-SHARP 1/4)

Try changing it to

(define-safe-public SEMI-SHARP 1.1/4)

or to

(define-safe-public SEMI-SHARP 1.1/4)

I won't promise that this will work, but it might.

Another possible work-around if this doesn't work is to put all of your
string 3 notes in a separate music expression and use part-combine to put it
with the rest of the notes.  That way, you can have the regular notation
written in the true pitch, and then you can transpose the tabulature notes
on string 3 to match the pitch in the stringTuning.

HTH,
