I'm surprised the cork pushed up the foil. With that cold and dry, cork should have shrunk and not gone up.
Wine is mostly water. When water freezes, it's volume increases. As the ice crystals form, they have to go somewhere, and will take the path of least resistance. The two options are break the bottle or push the cork up. Most of the time, I suspect the cork is pushed up rather than the bottle breaking.
