[O] ob-clojure: presentation of map structures?

How may I use an Org document to illustrate Clojure src blocks that produce Clojure data structures -- particularly maps -- as pretty-printed text?  I think I am using Org "master" in Emacs 24.3.

#+BEGIN_SRC clojure :results value <<what options?>>
  ["Peru" "Paris" "Sankt-Peterburg" "Philadelphia" "Plattsburgh" "Pluto"]

By the way, Clojure pprint makes the value into the following, which would be very respectable (with the addition of ":" org markup) as a result block in the Org buffer:

{"Pluto" 5,
 "Plattsburgh" 4,
 "Philadelphia" 3,
 "Putingrad" 2,
 "Paris" 1,
 "Peru" 0}

Floundering among the options, I tried :results value pp.  It yielded this:

: "{\"Pluto\" 5,\n \"Plattsburgh\" 4,\n \"Philadelphia\" 3,\n \"Sankt-Peterburg\" 2,\n \"Paris\" 1,\n \"Peru\" 0}\n"

pprint's good intentions are evident, but they collided with a superior force.
