Ummm.... no. They're not. You're misunderstanding what "scripted" means.
You approach a building, and when you reach a specific point, the building collapses due it being coded to do so.
The buildings are just there, and you destroy them at your own will, piece by piece with explosives.
For example: this piece of building will always be destroyed the exact same way...
BF3 with be reactive destruction, as you do something different it gets destroyed differently...
