Answer 1

1. Order by the desired column, then
2. Order in external query order by row number.
3. Use the function.

This function has logic for the last rownum order:

Select wmsys.wm_concat(t) CONCAT from 
(
    Select t from (
        Select t from (
            Select 'aa' t from dual
            union
            Select 'zz' t from dual
            union
            Select 'pp' t from dual
            union
            Select 'll' t from dual
            union
            Select 'mm' t from dual
            union
            Select 'xx' t from dual
            union
            Select 'cc' t from dual
        ) a 
        order by t
    ) order by rownum
) t
