What are the rules if a tie goes to penalties? presume a no score bonus?

From page 1, where one would normally find rules::

Pick the winning team correctly and you get 1 point. A bonus point is available for getting the margin of victory correct, within a 3-point band. Band 1 is 1-3 points, so if you pick 1, 2 or 3 point margin, you get the bonus point. Band 2 is 4-6 points; Band 3 is 7-9 points, and so on upward in 3-point increments.

Contestants need only pick the margin of victory in points, as was in the League competition. I’ll translate it to bands as I input the selections. So a pick that reads “Tyrone by 2” and if Tyrone win by 1,2 or 3 you get the bonus point in addition to the 1 point for getting the winning team correct. There is no additional bonus for getting the margin exactly right.

Extra time is not considered here…if Tyrone win by 2 after 70 minutes or after extra time, the margin of victory is 2. The only difference is for a game that is decided by penalties: the winning team is deemed to have a 1 point winning margin, no matter how many penalties are taken.
