Isn't this to do with the roll-n-time where the time in the blocks is adjusted to save getwork calls? It's not that they were generated in the wrong order, just that the date inside the blocks differ slightly from what the actual time was at that point.

The timestamp is created before the block is hashed, and only needs to fit within a broad window to be valid.  The timestamps are not required to increase from one block to the next.

P.S.  Please search next time.  There is no prize for starting the 1,000th thread on a common topic.
