While nothing would surprise me, even though it is working fine for me (giving full points) where are you checking this value?

You should be checking in Admin CP -> Users -> Search for User -> Username

The reputation value is reported (default is 10 usually.)

Then go give rep to that user, and reload the User page, check if the number reported goes up by the number of points you left.

Remember (for everyone out there, some may not be used to rep) there are two values. Reputation itself and "Rep Power"- Rep Power is a calculation based off the real rep value. There is no default option to show the real rep value in a postbit so if you are reading a number from the postbit it is more likely "Rep Power" not actual reputation.
