When you want to retrieve the key value in an input element that has a name array you need to do the following:

1
<input type="text" name="tag[1]" value="blah"/>

var tagSelect = [];
$('input[name^="tag"]').each(function(oneTag){
    var oneValue = $(this).val();
    var name = $(this).attr('name');
    var id = parseInt(name.match(/[0-9]+/));
    tagSelect.push(id);
});

Hope it helps you out.
