Pulling the high score and putting in the game?

I was able to submit my highest score to the server, but I would like to also get the highest score so the next user can see what they are trying to beat. Is this possible?

Not yet.

I think it would be a good idea for a future version of the base API if we could get the hiscores info from the server in a nice easy to use format. Then we could display the highest scores in the game, maybe with fireworks going off behind them :-)
