First, the fn sorted-map
<http://grimoire.arrdem.com/1.6.0/clojure.core/sorted_DASH_map/> is
variable argument and expects to be given (sorted-map :z 1, :b 2, :a 3) and
not (sorted-map my-map).
To use sorted-map, you'll need to do something like: (apply sorted-map
(mapcat identity my-map))
Second, when a clojure hash-map is used as a sequence, each key/value pair
is actually a MapEntry, which behaves like a vector of [key value]. So
your map fn is effectively doing (vector [1405961887 20]), which produces a
doubly-wrapped [[1405961887 20]] for each respective element.
