For test:

data as json file: test.json
function: $sort($, function($l, $r){$l.*.rank < $r.*.rank})

in jsonata onlyne work fine: https://try.jsonata.org/Of91H7T0M

[sergeevik]

in search some additional info:

in test data exist equeal values
{test.15={id=15, rank=4095}
and
{test.58={id=58, rank=4095}

if compare in js
4095 > 4095 = false
4095 < 4095 = false

for java comaparaot it is error

compare {test.15={id=15, rank=4095}} and {test.58={id=58, rank=4095}} result: false
compare {test.58={id=58, rank=4095}} and {test.15={id=15, rank=4095}} result: false
