I don't think so.  The empty string is equal to an arbitrary
string of {[20]}.   {[09]} is less, so I think a \t is less
than nothing.

The anomaly is letting teletypes determine the order of characters
after their death.  And, of course, collations are free to define
the ordering of white space as they choose.
