  You're correct. On a related issue, I hooked up the tip and ring to my
DMM and I'm getting 10V DC (loaded and unloaded). It's not unusual to see
~25% variance with unregulated wall warts (our AC wall is 122 VAC), but
10VDC is quite high, and I wonder if it's in spec.

When you say "prongs", are you referring to what plugs into the AC outlet?
If so, that's unrelated to the DC polarization. The AC is rectified into DC
and it's unimportant which side of the transformer gets the AC hot and which
gets the AC neutral.
