As I have tried to outline in an earlier mail, my conflict resolution 
strategy requires putting the pattern sets into a ranking by priority. 
The actual strategy looks like this:

   * At each hyphenation position apply the penalty from that matching
     pattern set, that has highest priority.  Here's some pseudo code:

     loop (over pattern sets in priority order)
       if (pattern set matches a hyphenation) then
          penalty = penalty[pattern set]
          break
       end
     end
     apply penalty to hyphenation
