      Syntax:

      {$project:{orderedArray:{$sort:{path:<array-returning-expression>[, sortBy:<someFieldInArray>, <ascending-vs-descending-option>]}}

      Examples it should work on:

      Input: {a: [ 1, 10, 5, 3 ]}
{newA:{$sort:{path:"$a"}}}
returns:  { newA: [ 1, 3, 5, 10 ] }

Input: { a: [ { x:1, y:99 }, { x: 9, y: 4 } ] }
{newA: {$sort:{path:"$a", sortBy: "$a.y" }}}
returns: { newA: [ { x: 9, y: 4 }, { x:1, y:99 } ] }
