For some reason, on Firefox 64.0.2, none of the answers worked for me. This is what worked in the end, a mixture of Joseph Silber and Jeaf Gilbert's answers:

var $wrapper = $('.testWrapper');

$wrapper.find('.test').sort(function(a, b) {
    return +$(a).data('percentage') - +$(b).data('percentage');
})
.appendTo($wrapper);
