Come on. It's the same question really. Answer remains the same too:

No matter what the game, whether JS Flash or native binary, if the scoring system is vulnerable, people will tamper if the game is good enough. Stick to clever serverside every time.

This is not a problem that can be solved by obfuscation at the client end. There's plenty of prior art concerning keeping high-score tables/game data secure. Sharpen your google-fu and have a look.

As I said in a previous answer, a secure system can not trust client score input. It doesn't matter whether the intended program is Flash or JavaScript. Once you send the program to the client they have any required key. So you can't rely on the client giving you accurate scores. The only reliable way to do it is to move score calculation to the server. Then, for a bot to play it still would have to calculate every movement manually.
