This is the tab for the version off of the Once soundtrack album–which is significantly different from the one off the Frames’s album, Fitzcarraldo. Both are great but I definitely prefer the solo acoustic version off the soundtrack.
The Open E tuning made figuring this one out significantly harder for me (my tuning experimentation involves all of dropping down a half step and I rarely even do that) so I set off on some searches and found good starting points. Eventually, I found this great video though which turned out to pretty much dead on as far as I can tell. I still didn’t see it tabbed anywhere to this extent so I figured I’d get it down and easier to find. Also, Travestees, who made the very helpful video, has also recorded a video of himself playing the actual song which is also worth checking out.
Tuning (low to high): E-B-E-G#-B-E
