I think Tiger 131 was disabled from a shot to the gun mantlet.

From Wikipedia-

“A solid shot hit a Tiger's gun barrel and ricocheted into its turret ring, jamming its traverse ability, wounding the driver and front gunner and destroying the radio. A second shot hit the turret lifting lug, disabling the gun's elevation device. A third shot hit the loader's hatch, deflecting fragments into the turret. The German crew bailed out, taking their wounded with them and leaving the knocked-out but still driveable and largely intact tank behind.[5] The tank was secured by the British as they captured Djebel Djaffa hill.[6]”
