Sort with -Infinity fails

Dear MathGroup,

Minus Infinity (-Infinity) is smaller than -8, but Sort does not sort it as
expected.
Is there a Real minus Infinity?


In[75]:=
      -Infinity < -8
Out[75]=
      True

In[76]:=
      Sort[{-Infinity, -8, 5}]
Out[76]=
      {-8, 5, -∞}


Regards,

Tom Aldenberg
