This works, but looks rather ugly :-)
scala> val m = Map() ++ List("s" -> (1,2), "t" -> (3,4))
m: scala.collection.immutable.Map[java.lang.String,(Int, Int)] = Map(s
-> (1,2), t -> (3,4))
scala> JsArray(m.map(x => JsObj(x._1 -> JsArray(x._2._1,
x._2._2))).toList:_*).toJsCmd
res20: String =
[{"s": [1, 2]
}, {"t": [3, 4]
}]
