You could send the server the entire run of the game - the start state
and every piece of input in between it and the end state.  The server
could then run through the game itself and generate the score that way. 
This sounds like a lot of data but if stored efficiently and then
compressed it might be all right, depending on the application.

It'd still be possible to hack this but much harder, cause each bit of
input affects the state after it and so changing one may actually
invalidate later pieces of input - at which point the server could throw
the log away.
