I don't think so, the sorting routines use a strict weak ordering:
[ 25.3]
"6 In the descriptions of the functions that deal with ordering relation-
  ships we frequently use a notion of equivalence to  describe  concepts
  such as stability.  The equivalence to which we refer is not necessar-
  ily an operator==, but an equivalence relation induced by  the  strict
  weak  ordering.   That is, two elements a and b are considered equiva-
  lent if and only if !(a < b) && !(b < a)."
