In general JSON maps are not ordered:

{ "a" : 1,
  "socks" : "black" }
is the same as
{ "socks" : "black",
  "a" : 1 }

Only arrays are ordered,
{ "socks" : [ "black", "green" ] }
is not the same as
{ "socks" : [ "green", "black" ] }

Hope this helps - if not, maybe send some short/simple test cases?
