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?>>
(zipmap
  ["Peru" "Paris" "Sankt-Peterburg" "Philadelphia" "Plattsburgh" "Pluto"]
  (range))
#+END_SRC

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.

Maybe try ":results pp org".

There was a discussion of this at the Clojure google group:
https://groups.google.com/d/msg/clojure/gthjNWfAWKo/aKwuqh2qx68J

The tabularization problem was resolved, but the pp of the map behavior
is not changed.  I tried a few permutations of :results options, and did
not get close to the Clojure pprint function.

The org manual says the pp option is "This
option currently supports Emacs Lisp, Python, and Ruby. E.g., :results
value pp."
