They made it 2-0 shortly before half-time when Matty Robson swung a free-kick into the box and Ian Harte was unmarked to nod the ball just inside the right-hand post for his 10th goal of the season.
Orient pulled a goal back in the 58th minute when James Scowcroft's shot from the edge of the area was blocked and the ball spun up to Jarvis who swivelled and blasted the ball high into the net from 12 yards giving keeper Adam Collin no chance with the power of the shot.
Orient's comeback continued in the 77th minute when Jarvis got his head to a cross from the right and Livesey, in trying to clear merely succeeded in heading the ball back past his own keeper into the net.
Livesey redeemed himself late on with a goal-line clearance when Nicky Adams looked to have grabbed all three points for Orient.
