Ah thanks. Seems the difference is that you guys hold the NM till all waves are over.

That gives you the additional:
All Melee Units Dispatched
All Mage Units Dispatched
No Beastmen Survivors

All of that totals 3000.

Good to know! Wish there was an english list of all the score elements.

Edit, wow you guys got 9 Dark Matter placeholders (no fireworks though)
