What do you think about using UIDs (or maybe some hash value of the buffer)
instead of serial numbers? It might help with other uses of t-filter to be able
to re-order the filter sections without re-compiling.

Thank you very much! It’s been a while since I wrote my last Lua code for
ConTeXt...
I’ll just update the LilyPond wiki page (and then delete everything about the
old LilyPond module).
