Over the last 2 weeks I have been testing this and found the solution. When I started the big problem with my high score contests was to make sure the scores are true scores and not change by players using special software. Once I did this I got serious Touch Arcade players to play and test my games. This is a big plus for developers and the players have fun competing against each other to win the cash prize. You can see the results in the Promo Codes And Contest Forum http://forums.toucharcade.com/showthread.php?t=266519
Now I have about 10 youtube videos show my game and a play by play how to score high. If this is helpful to your game consider it
This is my 2nd contest and I expect to have a number of youtube play by play videos from serious TA players. You can find the 2nd contest here http://forums.toucharcade.com/showthread.php?t=267030
