But are those scripts supposed to be used without runnig autogen.sh
(and implied configure) first?

I may have some time during the next two weeks and arrange things
so those scripts will use the python detected by (or passed via
environment to) configure. If you want it.

#!/usr/bin/env YOUR_FAVORITE_INTERPRETER

should not be used ever. At least not for scripts that will be
installed system-wide. And if possible, not even for local scripts
(like scripts/build in lilypond).
