Simple file rename script with date

I am new to scripting and am in need of a simple script to rename or copy a file from a constant file name to a date file name. IE: score01.txt to 101701.txt (todays date)
this is for a daily process. I couldn’t find a way in a batch file to do this. I am assuming it would be very easy in a vbscript file or something. It will be running on an NT4.0 box.
