SQL & PL/SQL

Hi Everybody,

how can I sort hierarchical queries by each branch?
I want to determine the order by myself e.g. with a
extra column. For Example I get from the query following:
root
|- A 3
|- A 5
|- A 1
...

But I want to get a sorted tree like that:
root
|-A 1
|-A 3
|-A 5
...

Thanx Thomas
