It's another a battery power lead.

Black = Ground
Red = +Battery (not required for Victors)
Yellow = PWM Control (1-2 ms positive going PWM signal)
Orange = +Battery

See page 8 of the the "2004 EDU Robot Controller Reference Guide" for a pictorial of the pinout.

I simply assume the orange lead is most likely a higher current capacity "Raw Motor Power" lead for the servo (vs a low current "Logic Power" wire or PCB trace that may or may not be regulated), but I haven't broken any seals nor set up any voltage and current inline tests yet to confirm that.
