Then I don't think I've ever seen a "standard" CV pedal.

The tip is the return (the voltage out of the divider in the pedal), so if
you use a regular TS 1/4" cable with the shield ground it will work fine.
You could also use a regular TRS cable -- the 5V ring will be ignored by
the jacks in the MOTM (although the Vortex will ignore any negative
voltages). You could also use an insert cable and ignore one end, and have
a 5V source for something else. No special cable is needed.
Don't we do enough soldering as it is?? :)

Actually, if the 5V gets connected to ground, it could care less -- that's
what would happen if the wiper in the pedal was all the way at that end.
