From: Zhou Zheng Sheng <zhshzhou@linux.vnet.ibm.com> ObjectStoreSession.get_list() just returns an unsorted id list. When the caller wants to sort the list according to a key, it has to implement the sorting code each time. This patch implement the sorting in objectstore to make the code re-usable.
