I had it happen with a Chaos.  I think it isn't so much the cold as moisture - the Chaos sat in a couple of inches of water when the basement flooded and that's where it discolored.

the key to this whole topic is to always leave your bowling balls in an area where they stay room temperature( 60-80 degrees ). the chemical combinations that make up modern bowling balls are very temperature sensitive.
