You van do this :
1.Create new table with exactly the same structure as orig table.
2.Create little php script which does this :
select * from origTBL
while($line=mysql_fecth_array($res)){
insert into newtbl values(............)
}
In the new tbl yuo will have the records ordered.
Than just rename the tables.
