seriously.... Mixer4 does a lot of exactly that, and is an offline, text-based program.
(think Lilypond, but for audio.)
it's new, not so well known yet, and not yet packaged for repositories, but is an
exciting little bit of code! i'll let Grekim speak for himself here, to answer any
questions about details...

I've been considering writing a make-like
tool, but would like know if
something existing fills the role. I haven't been able to find
information on using csound for mastering a few sections of audio, but
maybe that could work...
Not what you want, but using Ardour's automation, gain curves,
etc. combined with the 'export' facility amounts to some form
of scripting. I don't know of any command line tool that would
allow the same. If you want to apply some process on an audio
file from position A to B, the basic problem is to determine
A and B. Having a view on the actual waveform helps a lot to
do that. The only alternative I see would be some command line
player that allows to define markers, also offers some 'preview'
facilities such 'play from T - N seconds to T', 'play N seconds
starting at T', 'move T by N milliseconds', etc. etc., and then
offers some convenient way to store such information for later
use by off-line processing. I'd be interested to have such a
thing as well, but it takes a lot of programming to make it.
