I found it!!

********************

There's actually 3 leaderboards inside the competition. One is for 'winners', one if for 'scores' and one is for 'margins'.

Competition winners will be based on... the 'Tip the Winners' leaderboard.

In the event of a TIE - (which can't happen because I don't have enough prizes.. heh.. ) then to break the tie the leaderboard 'Tip the Scores' will be used, and if there's STILL a tie after that, the 'Tip the Margins' leaderboard will be used. If there's still a tie after all that - I give up and we'll do what they do in a rugby world cup final when they've exhausted their avenues... toss a coin :)

Okay.. so Keyte, shane oneill and Peter Edge all got 6 points on the Round 3 Tip the Winners leaderboard, so I had to go to the Tip the Scores leaderboard, and shane oneill's name comes up first out of those three. So congratulations shane on being our Round 3 winner - drop me an email so I can send you your $5 scratchie ticket!
