It's a nice tune, and it's in A dorian. This is the most common "minor" mode in traditional Irish and Scottish music, which is why it probably sounds Irish to your ears. The "Dorian" mode is basically similar to what the classical folks call "natural minor" (or "Aeolian"), but the 6th of the scale is sharp. It's actually a fairly common sort of scale in a lot of the world. To make it sound even more traditional Irish or Scottish, harmonize it with A minor and G major chords. It'll probably be obvious where to use each. Those two bars that read |g3ec2| might sound best with a C major chord. It's also inevitable that people will play it as a waltz.
