The part about Collada in our scene export limitations (written after talking with Conrad) suggests that vertex colors are indeed exported:

"The COLLADA export does not support text, silhouettes, or per-model clipping. It has been tested mainly on Macs, with proper rendering observed in Preview (Mac 10.8) and iBooks on iPad. Other applications (e.g. SketchUp and MeshLab tested on Windows) correctly handle the geometry but not the triangle vertex colors."
