DataGrid has a columns property that you can use.

private function reorderColumns()
{
    var columns:Array = dataGrid.columns;
    var dateColumn:DataGridColumn;
    var totalColumn:DataGridColumn;

    var filter:Function = function(element:*, index:int, arr:Array) 
    {
        if(DataGridColumn(element).dataField == "DATE") 
        {
            dateColumn = element;
            return false;
        }
        if(DataGridColumn(element).dataField == "TOTAL") 
        {
            totalColumn = element;
            return false;
        }
    }

    columns.filter(filter);
    columns.unshift(dateColumn);
    columns.push(totalColumn);

    dataGrid.columns = columns;
}
