While they should, there are also reasons why in some cases
you need sorted (address in strictly ascending order) hex files:

Some (if not most) targets have more flash than RAM and
thus are forced when doing in application programming, IAP,
to programm their nonvolatile memory while they receive the
data. (They cannot buffer the complete contents of the
memory to be programmed.)
Unsorted hex files can then cause redundant (and costly in terms
of time, user experience and eventually flash wear) clearing
of flash pages.
So it might be a good idea to read:

  3.1.2 Postprocessing the Intel Hex file
