Well, that's because the way I use it is actually the default.  Some
other scripts do use it to allow the service to run continually (such as
cron or postfix) and others use it set to the default or leave it out to
only start on demand (ssh, for example).  But I did try it with and
without having this key, which made no difference.

Right, which is why I added this to the amanda.plist.

I'm quite sure that the plist itself, as is, is correct.  It does work
just fine when I manually 'launchctl load' it, after all.  It just
doesn't start automatically, *even though* it's actually loaded
automatically.  That is, after a fresh reboot, 'launchctl list' will
show me that org.amanda.amanda is a service that is running, only it
will not actually be running and nothing is listening on port 10080.

That's exactly how I did come up with this plist. :-)

Well, if they're accurate, then I think they're fine.  But then, I've
noticed that on OS X manual pages are not always entirely accurate.  Or
complete.  Or necessarily existant.
