Limiting a number to 5 or 10 is no coincidence at all. There are a number of plausible explanation for doing this.

2. Also, there are effectively 20 levels in D&D and splitting that number up into half (10) or one fourth (5) gets you those same numbers.
3. Giving a person a penalty of -5 to attack isn't a huge surprise and won't be too painful. A first level melee character like a Fighter or Barbarian is likely to have around 18 strength and +1 BAB. That's +5 to attack, which is also the same number as the common video game Power Attack penalty.
4. The penalty to attack from Combat Expertise is -5. This is a feat that deserves the limitation since a character with high enough AC can get to the point where they're only hit 1/20 times. A party with a character of AC 40 and three of AC 20 creates an odd and difficult combination. This will be even more problematic if you're designing a computer game that isn't going to be modifying itself to artificially increase or decrease attack rolls based on the PC's AC.
5. Last and likely most relevant is the fact that we have 5 fingers and 2 hands. This may sound like a stupid reason to you, but its the real reason why we have a Base 10 math system. If everyone had 3 hands and 6 fingers on each, we would likely have a Base 18 math system and Power Attack would give a -6 penalty to attack. It's also the reason why our calendar was based on 10 months (before Caesar and Augustus changed it) and the reason for all sorts of other things in our lives.
Five is a very common number and it should be of no surprise to anyone that it would get picked out for use in almost anything.
