node.js - How to sort nested objects with arrays in MongoDB?

Question

If I have these two objects:

OBJECT A:

{
  ...,
  votes: {
    claps: [{ count: 10, }, { count: 5 }],
    hearts: [{ count: 5 }, { count: 2 }]
  }
}

OBJECT B:

{
  ...,
  votes: {
    claps: [{ count: 20 }, { count: 10 }],
    trophy: [{ count: 5 }]
  }
}

For instance, object A has a total of 22 votes, and object B has 35 votes.

I already have a function that, given an object, gets its total number of votes.

I also already have a compare function which returns 1 if greater, 0 if equals, and -1 if less than.

But it seems to me that Mongo's sort doesn't support giving it a compare function.

How would I go about sorting these type of objects in Mongo?
