Answer 1

Use:

var asc=false;   
var sorted=$('div').sort(function(a,b){
    return (asc ==
           ($(a).data('sort') <  $(b).data('sort'))) ? 1 : -1;
});
asc = asc ? false : true;
$('body').html(sorted);

Working Demo

Answer 2

Given that your data is integer based and the sort you need is ascending order, there is a neat way to do this with pure css :)

Just put your data divs inside a parent flexbox container and make your sort integer a css order property, like so...

<div id="container" style="display:flex">
    <div style="order:14">14</div>
    <div style="order:6">6</div>
    <div style="order:9">9</div>
</div>

Only works in 'modern' browsers though.

Check this out: http://jsfiddle.net/en107qxb/5/

    function sortUsingText(parent, childSelector) {
    var items = parent.children(childSelector).sort(function(a, b) {
        var vA = $(a).text();
        var vB = $(b).text();
        return (vA < vB) ? -1 : (vA > vB) ? 1 : 0;
    });
    parent.append(items);
}


  sortUsingText($('#sortThis'), "div");



function sortUsingData(parent, childSelector) {
    var items = parent.children(childSelector).sort(function(a, b) {
        var vA = $(a).data('sort');
        var vB = $(b).data('sort');
        return (vA < vB) ? -1 : (vA > vB) ? 1 : 0;
    });
    parent.append(items);
}
  sortUsingData($('#sortThisData'), "div");
