I was able to solve this. The key was using the <loopzoneattribute occupancyschedule=""> as the sensor Object IDF name. This caused DesignBuilder to look up the occupancy schedule for each zone. My final working code is below, which randomizes both the occupancy and the internal equipment power level.
