Without you being a little more specific about the kind of scoring that you want, how you want it displayed, what kind of game its for and things like that it's hard to tell you anything specific at all.
For an example of a simple scoring system in action in a game, have a look at the Dark Invaders tutorial example that comes with DarkGDK, it uses a bitmap font system to display its score, but the system is fairly simple and you could use it quite easily or something like it in whatever kind of game you like.
If it ain't broke.... DONT FIX IT !!!
