There are several ways in increasing your score, or points as u put it, population and recruit units are the two most common and fastest ways, you can also get score through power
30 infantry = 3 power = 30 score
10 vehicles = 3 power = 30 score
10 tanks = 3 power = 30 score
It doesn't matter weather your units are armor, damage, or range, they all give u the same amount of power and score.
A resource field will give you 0.2 power = 2 score.
A relic will give you 1000 score, no power.
A crystal will give you 20 score, no power.
25 workers will give you 1 power = 10 score
I'm not totally sure about the numbers and if I'm wrong someone will correct me later but I hope this helps!
