sorting texinfo indices?

[Mark Polesky]

In scm/documentation-generate.scm, I find this:

 146 @appendixsec Function index
 147 
 148 @printindex fn

...from which texinfo magically generates IR A. "Indices":
http://kainhofer.com/~lilypond/Documentation/internals/Indices.html

I'd like the list (and others like it) to be sorted according to
the algorithm in scm/lily-sort.scm. Judging from recent threads, I
figure some python tweaking would be necessary? I'm not about to
learn python, but does anyone know how this could be done?

Thanks.
