Sort an object based on specific key

[TranceGeniK]

Currently the value has to be set to an array, but would it be possible to sort an object ? Given the following data structure :

{
  "menu": {
    "entry_a": {
      "order": 0
    },
    "entry_b": {
      "order": 1
    },
    "entry_c": {
      "order": 2
    }
  }
}

Would it be possible to update the sortable list based on the "order" key ?
