#5 is a little ambiguous.
I read "Tie", in that context, to mean "Tie Game" or a "Push" (when the spread is taken into account). In other words if there were 14 games and a member correctly picks 13 of them and the 14th game is a push (tie) then they would be eligible for that weeks case only.
However I completely see how it can be read the other way as well. Although #4 & #5 would seem to contradict each other if that was the case.
