Great!  No, nobody else has expressed any interest.

I'm not certain if you downloaded the source files or whether you're 
modifying the copy of scm/script.scm that's inside your local LilyPond 
installation.  Either of them would work, and if you're not comfortable 
with diff, you can simply send me your entire modified file.

One advantage of modifying scm/script.scm inside your local LilyPond 
installation is that then you can easily test the results (without 
compiling lilypond).

Unfortunately I don't know.

That sounds like the right approach to me.  If you're particularly 
uncertain about a setting, you could add a comment to that affect.
;; guessing?

If it's an important articulation then it's probably already defined; if 
it isn't defined and you guess a wrong value, we'll get a bug report 
about it that I can easily fix.
