Performing a manual sort on an array

I am using OpusScript which is very similar to Javascript.

I need to sort an array by two properties of the objects inside it.

The array object type is "ScoreEntity" with the Score and Time properties. I need the highest score at index 0 of the array, and vice versa, with faster times exceeding matching scores.

I've been trying to do this for ages and I can't get around it, I have Saturday syndrome!

ANSWER:

In the end I used BubbleSort, any comments on improving this are appreciated.

function SortScoreArray(array)
{

    var unsorted = true
    while (unsorted)
    {

        // Tracks whether any changes were made, changed to false on any swap
        var complete = true
        for (var i = 0; i < array.length - 1; i++)
        {           

            // Holds the value for determining whether to swap the current positions
            var swap = false

            var currentItem = array[i]
            var nextItem = array[i + 1]

            if (currentItem.Score == nextItem.Score)
            {

                // The scores are the same, so sort by the time
                if (currentItem.Time > nextItem.Time)
                {
                    swap = true
                }

            }
            else if (currentItem.Score < nextItem.Score)
            {
                swap = true
            }


            if (swap)
            {
                array[i] = nextItem
                array[i + 1] = currentItem
                complete = false
            }

        }

        if (complete)
        {
            unsorted = false
        }

    }

    return array

}
