I need correct MIDI output. And putting "b" wouldn't work if 
there was a B-sharp before it. Not that I compose with B-sharps
and B-flats in the same measure, but it needs to be a generic
solution.

And about the \tweak problem, I should have warned you...

http://lilypond.org/doc/v2.13/Documentation/user/lilypond/The-tweak-command
Notably the \tweak command cannot be used to modify stems, beams
or accidentals, since these are generated later by note heads,
rather than by music elements in the input stream.

But thanks for trying. This is a tough one (for me).
