I've added your code with minor modifications to CVS.  Is this code
production quality (ie. ready for unsuspecting users)? If so, some
documentation should be written as well -- a section should be added
to the reference manual, and perhaps, if applicable an example in the
tutorial.

see ly/engraver-init.ly in CVS.

Probably.

It's more a musical than a typographical property, so I think it does
not belong in the back end. You could run user code to produce the
letters iso. numbers, eg.

        SCM proc = get_property ("tablatureFormat");
        SCM text = gh_call3 (proc, scm_string, get_property
          ("stringTunings"), scm_pitch)
        note_head->set_grob_property ("text", text);

and then you could plug you own formatting functions  by setting

    tablatureFormat = #my-tablature-format-function .. 

I would be very glad if you would make that change as well.
