You could use the Helmholtz-Ellis notation because the arrows are a 
subset of it and you haven't specified what the inflection should be so 
a comma should be good enough.  But it should be simpler than that.  The 
arrowed glyphs are in Lilypond's standard font.  All you need is to 
define a new language with whatever pitch inflections you want, and a 
list of accidentals using the right glyphs.  This should have been done 
before, or there's not much point in having the arrowed glyphs, but I 
don't know where.
