It works for me.  Doesn't it work for you?

>From the fine manual (section 5.9. Comparisons):

  Comparisons can be chained arbitrarily, e.g., x < y <= z is
  equivalent to x < y and y <= z, except that y is evaluated
  only once (but in both cases z is not evaluated at all when x
  < y is found to be false).
