Hmmm.. this might be a bit late, but I thought you where trying to do this 
in a ZClass.. you can override the Folder's methods doing just this. Just 
define a new manage_main DTML method, add your ordering methods, add some 
External Methods to handle the reshuffling, and you'll be fine. Yes, 
self._objects = objects is thread-safe, the ZODB takes care of that.
