Does this sort exist?

it should still fix some issue You've reinvented a variant [*] of counting sort.
This is not a comparison sorting algorithm, so the Ω(n log n) lower bound on the worst-case number of comparisons does not apply: this algorithm can indeed run in fewer operations, provided certain conditions are met:
code :

seems to work fine It depends what you want to do when a hash doesn't have sorting key. I can imagine two scenarios:
1) exclude the hash from sorting
code :
arr.delete_if { |h| h[:key_to_sort].nil? }.sort_by { |h| h[:key_to_sort] }
arr.sort_by { |h| h[:key_to_sort] || REALLY_SMALL_OR_LARGE_VALUE }
if a key exist, sort it to be the last element of array

To fix this issue , Try this:
code :
if (isset($ar['key']))
{
    $temp = $ar['key'];
    unset($ar['key']);
    $ar['key'] = $temp;
}

I wish did fix the issue. Suppose $object is your original array, and $sort is the array with which you want to manipulate the original array, the solution would be like this:
code :
function mergeArrays($array1, $array2){
    $newArray = array();
    foreach($array1 as $v){
        if(!array_key_exists($v, $array2)){
            $newArray[$v] = 0; 
        }else{
            $newArray[$v] = $array2[$v]; 
        }
    }
    return $newArray;
}

foreach($object as $key => $array){
    $object[$key]['data'] = mergeArrays($sort, $array['data']);
}

// display $object array
var_dump($object);

it helps some times I was able to get this to work by just specifying the type of res as []
code :
this.getConcept().subscribe((res:[]) => {
    res.sort((f, n): number => {
        if (f.code < n.code) return -1;
        if (f.code > n.code) return 1;

        return 0;
    }); 
    console.error(res);
    this.arrConcept = res;
});
(res:IConcept[]) => { ... }

Hope that helps It seems at the XQuery level you can change let $examples := $data/tei:TEI[@type="example"] to
code :
let $examples := sort($data/tei:TEI[@type="example"], (), function($e) { $e/@xml:id })
let $examples := for $e in $data/tei:TEI[@type="example"] order by $e/@xml:id return $e
