You're probably losing seal on the rings in your 3rd cylinder... add a few drops of oil through the spark plug hole, then run your compression test again. If #3 comes up in line with the other 3 cylinder, it's probably your rings.

A leakdown test will definitely tell you more about what's going on, but a standard compression test is always the first step.
