Since I have a major interest in getting ASCII MOCs out of the door
(it's a prerequisite for VODataService 1.2), I went ahead and just
wrote a validator.  I've put it onto volute (and even though the
standard itself is non version-controllable, it might be useful to
just put it next to it):

The validator only has a very basic command line interface: It will
validate its standard input, unless it is called with "test" as a
first argument, in which case the built-in tests are run.

Comments are welcome (and yes, 0/1,2 4

 12 *is* a valid ASCII MOC; I'm not enthusiastic about that, too, but
breaking existing software is uncool, so I guess we'll have to live
with it).
