JSON parse auto sort number object keys problem

Question

I have a interesting problem. I am working on an object which returns from my webapi in json format.

JSON Object

{"3852":20.0,"2852":20.0,"1852":59.0}

Above code is my original json code. It is auto-sorted when I run the code below on it, however:

JSON.parse('{"3852":20.0,"2852":20.0,"1852":59.0}')

I don't want it to be sorted when I run the json.parse function.
