You can arrange them in CustomizeLegend event.

Add OnCustomizeLegend="Chart1_CustomizeLegend" to your Chart markup or bind it in code behind. Then create handler:

protected void Chart1_CustomizeLegend(object sender, CustomizeLegendEventArgs e)
{
    //change order of legend items
    var items = e.LegendItems;
    var item = items[1]; //s2
    items.RemoveAt(1);
    items.Insert(2, item);
    item = items[1]; //after removing s2, s3 is now here
    items.RemoveAt(1);
    items.Insert(4, item);
    //etc...
}

Or you can create some collection first and fill it by referencing existing legend items in desired order, then clearing LegendItems and inserting all items at once. I think you can write it in a way it will be valid for all items number, but I leave it to you ;).
