No idea.

You're confusing "make efforts to change the order" and "don't make 
efforts to preserve the order".

Let's take a simple example: background.  Internally this is stored as 
values for background-position, background-image, etc, with no 
particular ordering imposed on them (they're just members of a struct). 
  The original string is not stored anywhere, since it's not needed for 
normal operation and would take up extra memory.  When asked for 
.background, Gecko just serializes this unordered representation, which 
implies picking an arbitrary order at that point.
