The method can be made more efficient by not doing two comparisons and instead using a the built in comparison method:

<code>

"protocol: *SortFunctions-Core-comparing"
threeWayCompareTo: aString
   "Do a three-way comparison between the receiver and aString, returning
   -1 if self < aString
   0 if self = aString
   1 if self > aString
   This assumes a total order in accordance with the mathematical law of trichotomy.
   See also: http://en.wikipedia.org/wiki/Three-way_comparison"

   ^ (self compare: self with: aString collated: AsciiOrder) - 2

</code>
