The difference (in percentage) is more important than the actual numbers. You have a large variance with #2 and #3, so make sure the valves are closing fully. you can try injecting a couple ounces of clean engine oil through the spark plug hole and repeat the test on the low cylinders. If compression increases, that can indicate waorn rings. If compression remains the same, that can indicate leaky valves, or possible mechanical damage to heads, pistons, or cylinder walls. Given the relatively low mileage, I would tend to think it is a valve sealing problem.
