Vikas: If you want to FORCE the order you can do couple of things like having a big PCTFREE (to make sure that no rows are migrated because of the updates) and small PCTUSED so that the blocks are never reused.
In this case records will be stored in (close to) ordered manner and SELECTs will return the rows in the way it is inserted. ( THis is not a fool proof method since parallel DMLs will not work as expected!!)
