Further investigation indicates that the problem occurs only
when I move a message to the end.  The presentation order is
saved if I haven't done that.  For example:
I start with my INBOX looking like this:
------------------------------------------------------------------------
   1       solomon@li Mar  5 ghh@Prince "Re:  Naturalized Philosophy of Science in SF"
   2    R  root       Mar  6 ghh        "latest on email in emacs"
-> 3       kyle@wendy Mar  6 bug-vm@uun "VM 5.25 -> 5.26 patch: message presentation order still not retained"
------------------------------------------------------------------------
Then I move 1 over 2 to get this:
------------------------------------------------------------------------
   1    R  root       Mar  6 ghh        "latest on email in emacs"
-> 2       solomon@li Mar  5 ghh@Prince "Re:  Naturalized Philosophy of Science in SF"
   3       kyle@wendy Mar  6 bug-vm@uun "VM 5.25 -> 5.26 patch: message presentation order still not retained"
------------------------------------------------------------------------
Then I quit from VM.  Then I restart VM.  And the change is
saved!
------------------------------------------------------------------------
-> 1    R  root       Mar  6 ghh        "latest on email in emacs"
   2       solomon@li Mar  5 ghh@Prince "Re:  Naturalized Philosophy of Science in SF"
   3       kyle@wendy Mar  6 bug-vm@uun "VM 5.25 -> 5.26 patch: message presentation order still not retained"
------------------------------------------------------------------------
But I now move the first message to the end in two steps.
------------------------------------------------------------------------
   1       solomon@li Mar  5 ghh@Prince "Re:  Naturalized Philosophy of Science in SF"
   2       kyle@wendy Mar  6 bug-vm@uun "VM 5.25 -> 5.26 patch: message presentation order still not retained"
-> 3    R  root       Mar  6 ghh        "latest on email in emacs"
------------------------------------------------------------------------
I quite from VM.  I return to VM:
------------------------------------------------------------------------
   1       solomon@li Mar  5 ghh@Prince "Re:  Naturalized Philosophy of Science in SF"
   2    R  root       Mar  6 ghh        "latest on email in emacs"
-> 3       kyle@wendy Mar  6 bug-vm@uun "VM 5.25 -> 5.26 patch: message presentation order still not retained"
------------------------------------------------------------------------
This time the order is not retained.  Nor is it retained if
I move message 2 to the end.

However, things are OK if (instead of moving message 2 to the end) I
move message 3 backwards one step!  Then message order is
retained.  Message order is also retained if I move message
2 backwards into position 1.  So, it seems that the only
problem occurs when a message is moved forward into final
position.
