Am I right that this a a stereo jack with the mono signal on ring?
If so, why would anyone wire up a jack this way? A mono plug would short the signal to ground.

Well, one reason is that the jack is labelled "Speaker" and not "Speakers" and it is a mono radio. It's not like you can look down the hole and see what's what.

The jack is a standard tip, ring, sleeve jack, and the configuration looks good.
The real question is: Why would someone put a "tip and sleeve plug into it, when it *clearly* is intended for a tip, ring and sleeve plug?

Could it somehow disconnect the main speakers? You know, like the older stereos where you plugged in headphones and they automatically cut the main speakers.

There is an independent LINE-OUT with a lower amplitude version of this signal fed to tip and ring of a separate stereo jack, with 100 ohm resistors on each leg. This is a common technique that accommodates a stereo or mono plug.
The presence of the LINE-OUT jack wired so competently makes the SPKR-OUT wiring especially puzzling.
