All namespaced event's get sorted when they are stored/called. I've got a test page attached, but the following code snippet should suffice:

$(document).ready(function(){

$(document)

.bind('namespace.a.b', function(){

console.log('Called a.b');

})

.bind('namespace.b.a', function(){

console.log('Called b.a');

});

Shows 2 events, both with type a.b

console.log($(document).data('events'));

console.group('a.b');

$(document).trigger('namespace.a.b'); Should only trigger a.b

console.groupEnd();

console.group('b.a');

$(document).trigger('namespace.b.a'); // Should only trigger b.a

console.groupEnd();

});
