There are plenty medium scales out there, you will find one :-)
Tip van Flip: Generally with this body shape the bridge is between the volume knobs, closer to the bridge volume knob and the tailpiece about the same where the 5 pin is on long scales. With medium scales the bridge is closer to the neck volume knob and the tailpiece above the 5 pin.
