A jak byłoby w sytuacji:

sort_order = ['transport', 'accommodation', 'activities', 'extras']
items = [ 
  {:level1=>'b',:x=>'B1',:service_name=>'transport'},  
  {:level1=>'c',:x=>'C1',:service_name=>'extras'},  
  {:level1=>'c',:x=>'C2',:service_name=>'transport'},  
  {:level1=>'a',:x=>'A1',:service_name=>'activities'},
  {:level1=>'a',:x=>'A3',:service_name=>'accommodation'},
  {:level1=>'a',:x=>'A2',:service_name=>'travel'},]

W tym wypadku chcę posortować wg :level1 oraz sort_order...
