Firebase sorting not working

I'm missing something or Fireabase just isn't sorting at all ??

https://dinosaur-facts.firebaseio.com/dinosaurs.json?orderBy=%22height%22&print=pretty

{    
  "bruhathkayosaurus" : {
    "appeared" : -70000000,
    "height" : 25,
    "length" : 44,
    "order" : "saurischia",
    "vanished" : -70000000,
    "weight" : 135000
  },
  "lambeosaurus" : {
    "appeared" : -76000000,
    "height" : 2.1,
    "length" : 12.5,
    "order" : "ornithischia",
    "vanished" : -75000000,
    "weight" : 5000
  },
  "linhenykus" : {
    "appeared" : -85000000,
    "height" : 0.6,
    "length" : 1,
    "order" : "theropoda",
    "vanished" : -75000000,
    "weight" : 3
  },
  "pterodactyl" : {
    "appeared" : -150000000,
    "height" : 0.6,
    "length" : 0.8,
    "order" : "pterosauria",
    "vanished" : -148500000,
    "weight" : 2
  },
  "stegosaurus" : {
    "appeared" : -155000000,
    "height" : 4,
    "length" : 9,
    "order" : "ornithischia",
    "vanished" : -150000000,
    "weight" : 2500
  },
  "triceratops" : {
    "appeared" : -68000000,
    "height" : 3,
    "length" : 8,
    "order" : "ornithischia",
    "vanished" : -66000000,
    "weight" : 11000
  }
}

The heights are not sorted, is returning [44,...,0.6,...,3]

The request returns the result as a JSON object and there is no way to express the ordering, so the orderBy parameter cannot be used for ordering the results.

The orderBy parameter is expected to be used in conjunction with filtering parameters like equalTo.
