Sort array using another array in Javascript

I have got an array like this:

[1, Stopped]
[2, Waiting]
[3, Finished]
[4, Stopped]
[5, Running]

The number is the id of the program and the text is the status of the program. I need to sort this array according to the next order:

['Error','Halted','Blocked','Finished','Waiting to Start','Waiting','Stopping','Running','Idle','Stopped','Opened','Ready'];

Can anyone tell me how I can sort the array using the predefined order?

It is working in all different browsers except for IE8. Can anyone tell me how to sort it in IE8

You can use this:

if (typeof Array.prototype.indexOf !== 'function') {
    Array.prototype.indexOf = function (el) {
        for (var i = 0; i < this.length; i += 1) {
            if (this[i] === el) return i;
        }
        return -1;
    }
}

var a = [[1, 'Stopped'],
[2, 'Waiting'],
[3, 'Finished'],
[4, 'Stopped'],
[5, 'Running']];
var order = ['Error','Halted','Blocked','Finished','Waiting to Start','Waiting','Stopping','Running','Idle','Stopped','Opened','Ready'];

a.sort(function (a, b) {
   return order.indexOf(a[1]) - order.indexOf(b[1]);
});
