I don't tend to see the scrambling until it's done (: too focussed on
the keyboard! What seems to be the case is that the problem happens
during an auto save - so emacs won't be responsive, when it comes out
of that pause, the letters buffered up appear but not in the correct order. I
have a fairly large INBOX (in vm) that I sometimes don't save for a
bit so auto saving can take a few seconds.

I've just seen it happen in a .tex buffer so it happens in more than
just mail-mode.
