Sorting JSON data client side

Question

I have the following script which combines 2 feeds together:

$(document).Ready(function() {
    url = 'feed 1';
    url_2 = 'feed 2';

    $.when(
        $.ajax({
            type: "GET",
            url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=1000&callback=?&q=' + encodeURIComponent(url),
            dataType: 'json'
        }),
        $.ajax({
            type: "GET",
            url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=1000&callback=?&q=' + encodeURIComponent(url_2),
            dataType: 'json'
        })
    ).done(function(a1, a2) {
        var data = a1[0].responseData.feed.entries.concat(a2[0].responseData.feed.entries);
        if (data[0]) {
            for (i = 0; i <= data.length - 1; i++) {
                document.write(data[i].title);
                document.write("<br>");
                document.write(data[i].categories[0]);
                document.write("<br>");
                document.write(data[i].publishedDate);
                document.write("<br>");
                document.write(data[i].link);
                document.write("<hr>");
            }
        } 
        else {
            document.write("No records");
        }
    });
});

How do I go about sorting the joined feeds by publishedDate?

I think I'm supposed to use jquery.sort, but can't figure out how to use it with my current code.

You could do something like this

data.sort(function (a, b) {
    if (a.v > b.v) {
        return 1
    }
    if (a.v < b.v) {
        return -1
    }
    return 0;
});

Notes

change v to the variable name of the published data
data should be an array of the feeds

This seems to be giving me strange results, i.e. 12 aug 2013, 16 sep 2013, 12 may 2013. I was expecting, 16 sep 2013, 12 aug 2013, 12 may 2013.

@oshirowanen change the return 1 to return -1 and vice versa

Still seems completely random, i.e. in the same month and year, I am getting 19, 22, 15 of september 2013, then 12 may 2013?

@oshirowanen can you create a jsfiddle, and then I will give it a bash there
