Hm, 'man bash' clearly states in section "Conditional expressions" 
(that's what is included in [[ ... ]]):

string1 < string2
  True if string1 sorts before string2 lexicographically in the current 
locale.

arg1 OP arg2
  OP is one of -eq, -ne, -lt, -le, -gt, or -ge.  These arithmetic 
binary operators return true if arg1  is  equal  to,  not equal  to, 
less than, less than or equal to, greater than, or greater than or equal 
to arg2, respectively.  Arg1 and arg2 may be positive or negative integers.

Personally, I like the bash documentation because it is complete and 
concise.

Greetings,
Bernd
