[O] Positioning of Tags on Header ?

[David Masterson]

How does Org position the Tags on the Header line when it reads in an
Org file with Tags?  It seems that the Tags move from time to time and
that can actually cause the file to be viewed as "changed" by the change
control system (CVS).  I would've thought that the Tags are positioned
when inserted and then left alone.  Is something else happening?
