Perhaps this is an amend-record? (That is, META1 was added, recorded,
moved and then amend-recorded.) Sometimes darcs creates subtly different
patches than you would expect in such situations.
Moves are tricky no matter what, particularly because I think that
--xml-output sometimes does reorder the primitive patches into nice sort
orders that also make it tougher to follow the actual operations. Have
you compared ``darcs annotate -p 'The name of the patch in question'``
(or the 'p'ager operation in ``darcs changes -i``) to see if the order
of primitive patches makes more sense there? If that is the case it may
be useful to check the bug tracker for an issue on this reordering (I
think there might be one) or otherwise file a new one.
As for a better way to do what you are doing: if I knew the context of
what you are doing I might suggest you take some other approach or just
handle gracefully any error conditions you are dealing with. I've got a
feeling that what you are trying to do is not necessarily what you want
to be doing...
