There's also (sorted-map-by ...):

user=> (doc sorted-map-by)
-------------------------
clojure.core/sorted-map-by
([comparator & keyvals])
  keyval => key val
  Returns a new sorted map with supplied mappings,
  using the supplied comparator.


So you can write a less stringent comparator if you like and use that to 
side-step this sort of exception.
