For myself, I only keep score in games. In fact, it's a good tell for me; whether I'm keeping score or not. For example, when I was catting around purely for fun, I kept score. When sex became a coping mechanism? I quit counting. When it would go back to being a sport, I started counting again. When sex became this deeply meaningful thing in a committed relationship? Also quit counting. But if we were having a bit of fun over the weekend, turning sex into a game for whatever reason, I may very well start counting just in that instance. It may even become an inside joke. But that would only be a facet of our sexlife. Not the whole of it.
When something is qualitative, rather than quantitative... Or when it's meaningful or necessary... I don't keep score. It's not about winning. It's about being.
If I've gotten to the point where I need a win? Things are bad.
If I've gotten to the point where I'm assigning numbers to things? Things are either meaningless or lighthearted.

ETA : I was married to an engineer. I had to break everything down with him into black and white, numerical values, quantitative things. My son is a numbers-guy. He's actually taught me to see the beauty in numbers, programs, equations, code. I can understand that some people who see the world like that. It's neither good nor bad, just simply is. But my mind simply doesn't work that way. Both my ex and my son transmute quantitative into qualitative. It's pretty fascinating to see the things they can create that way. Of course, my ex is a sick SOB who keeps score with people, having to win conversations and score points over people to raise himself up by putting others down. Static equations. In order for one to rise, another must fall. My son uses the same kind of mind to do things entirely differently. He uses his thought processes synergistically. Instead of putting others down, he does the whole 'tide raises all boats' kinds of things. He adds things together until the sum is greater than the whole of its parts.
