CAML QUERY ORDERBY IS NOT WORKING

SPWeb _SPweb = _SPSite.OpenWeb(); SPList _SPlist = _SPweb.Lists[FL.ToString()];

                    SPQuery _spquery = new SPQuery();
                    _spquery.Query = "<Query><Where><Eq><FieldRef Name='Title'/><Value Type='Text'>now</Value></Eq></Where><OrderBy><FieldRef Name='Date_Of_x0020__Posted' Ascending='False' /></OrderBy></Query>";//"<Query><OrderBy><FieldRef Name='Date_Of_x0020__Posted' Ascending='false' /></OrderBy></Query>";///CAMLquery  for oderby posted date


                    SPListItemCollection FaqCollection = _SPlist.GetItems(_spquery);


                    if (FaqCollection != null || FaqCollection.Count <= 0)
                    {

                        foreach (SPListItem item in FaqCollection)

                      {

}

}
