Result order

Is it good to demand result be ordered as an input while input is just a Dict?

When I fix my code to meet assert tests, I've pass it but got an error on checks:

Fail:undefined({
    "silver coin":{
        "price":10,"amount":1000,"weight":20},
    "ruby":{
        "price":1000,"amount":2,"weight":200},
    "golden coin":{
        "price":100,"amount":200,"weight":50}},
    5)

Your result:["ruby: 2","golden coin: 92"]

Right result:["golden coin: 92","ruby: 2"]

Whose result is right finally?

I suppose bag shouldn't be ordered (my bag IRL is semi-ordered at least)
