I'm by no means a Waf expert. Building Geany with Waf is very easy,
much easier than fighting with autotools.
Anyway, that's not really what you have asked :).

Actually, wscript's are no programs and also actually don't need a
shebang. Not sure why Geany's has one, probably because I copied&pasted
it from somewhere else :).
Anyway, for filetype detection can also be done easily use
~/.config/geany/filetype_extensions.conf, e.g. in my personal config,
part of the setting for Python files is ";wscript;SCons*;".

IMHO this is far beyond Geany's scope especially because this seems to
be a very special use case to me.
Generally, I'd say either we make the filetype system more flexible
what Nick has already begun (wow!) or maybe your use case could be made
into a plugin, not sure.
Unfortunately, I don't have as much time as I would like to have to
read, discuss and even actually code as much as I wish...but you know
the game, real life...
