Sorting an Object Array by it's Title. Flash - Actionscript 2

I have an array of objects. My object has it's title inside of it as a reference. I need to sort my array of objects in Alphabetical order by title.

Below is what I've been playing with, trying to accomplish this goal. As an example, i stored the title reference on my array objects as index 0. On index 1 i stored an ID reference just to check against the result of my sorted array.

The last output I'm getting from flash, is ordered in such a weird way that makes absolutely no sense to me. Please help! I'm open to different methods of accomplishing the same goal.

//This is an example list of my objects, and their test titles.

var obj = Array("ants", 24);
var obj2 = Array("cants", 29);
var obj3 = Array("xants", 35);
var obj4 = Array("bants", 80);

//Hear I assign each object to an array
var test = Array(obj, obj2, obj3, obj4);

//I create 2 arrays. 1 to store the titles in, and 1 for the object itself.
var alpha_sort = Array();
var obj_index = Array();

for(var i in test){//loop through all properties
    alpha_sort.push(test[i][0]);
    obj_index.push(test[i]);
}

trace('----- Display unsorted list ------');

for(var i in alpha_sort){//loop through all properties
    trace(i+' - '+alpha_sort[i]);
}

trace('----- Display sorted list ------');

alpha_sort.sort(2);
for(var i in alpha_sort){//loop through all properties
    trace(i+' - '+alpha_sort[i]+ ' - '+obj_index[i][1]);
}

The Output is:

----- Display unsorted list ------
3 - ants
2 - cants
1 - xants
0 - bants
----- Display sorted list ------
2 - bants - 29
1 - cants - 35
0 - xants - 80
3 - ants - 24

You can do this by either converting your array values to objects (instead of sub arrays) and using the sortOn method, or creating a custom sort function.

I'd reccomend to prior: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/2/help.html?content=00000751.html

var test = Array({title: "ants", value: 24}, {title: "cants", value: 29},{title: "xants", value: 35});

test.sortOn("title");

To use a custom sort function:

test.sort(sortTitle);

function sortTitle(a, b):Number {
    if (a[0] < b[0]) {
    return -1;
    } else if (a[0]>a[0]) {
    return 1;
    } else {
    return 0;
    }
}
