I guess because it makes a convenient wrapper?

They certainly would the way I had it. Your suggestions give a lot of food 
for thought.

My natural tendency is to want the version_cmp method in String and 
version_sort in Array... would it make more sense to simply do:

class String
  def version_cmp(b)
    #compare(self,b)
  end
end

class Array
  def version_sort
    self.sort{|a,b| a.to_s.version_cmp(b.to_s)}
  end
end

That would save the step of extending those classes in code.
