Req: simple scoring stuff

Does anyone have some relatively simple scoring examples?

I'd like to try and learn more about this functionality, but the man page is  
not very clear to me (it might be clear as crystal to you, that's not what  
I'm saying).  I don't grok man pages very well anyway, try as I might.

Also the best examples are the ones people are actually using.

Pointers gladly accepted.

Thanks
