Yes, as a general rule, for two reasons:

- It helps to reduce conflicts when two people add two different header
  files at a later date (provided they don't ignore the sorting and add
  them both at the end of the list.)

- It helps reduce the chance of having the same include listed twice
  (sometimes silently caused at git merge time) since it means if two
  people independently add the same include in the same place in the
  list, git will cope.  Eg, if one adds an include in one random place
  in the list, and someone else adds the same in another random place in
  the list, the result will be two includes of the same file.  If they're
  sufficiently far apart, git will not flag a conflict.
