[Oracle] Hi, how can I preserve the sort when selecting from an inner subquery?

As my title states, I am querying a table and using an Oracle analytical function to group and order by.
End-game here is to load from this select statement. But the target table does not have the ORDRED_ROWNUM column.
How can I preserve the sort done by that function, if I say, only select COL1, COL2 from the inner query? Because if I just grab COL1, COL2, they are not in the same order as the set from the inner select.
Edit: Solved, ORDER BY ORDRED_ROWNUM, in the outside query, thanks to Cal1gula

My latest supply thesis:

Fam, I have a new thesis (and yes, this (for now) pertains mostly to BTC at this point but will be massive for all crypto):
We see increasing press about Michael Saylor’s $700M bitcoin investment. His rationale centers around ONE THING: debasement of the dollar and thus a decrease in the value of cash holdings. That’s it.
During his recent interview, he brags about his eight houses, seven yachts, etc. He has it all… literally. So now his attention turns to PRESERVATION of value for his company, shareholders AND the generational wealth he has for him and his family.
So, this trail-blazing example I believe will catch on. Soon, it will be held that is is not only fiscally responsible for companies to start hedging their cash reserves with crypto, but for family offices and individual million and billionaires to “of course” hold crypto as part of their portfolio to hedge against currency debasement. Fidelity and JP Morgan Chase are now actively promoting crypto as part of a responsible investor’s portfolio. Think about that. So of course, the big players like:
Stanley Druckenmiller
Paul Tudor Jones
David Tepper
Bruce Kovner
Ray Dalio
Jeffrey Gundlach
George Soros
Howard S. Marks
Bill Lipschutz
John Paulson
Julian Robertson
Jim Rogers
Bill Ackman
Leon Cooperman
...are going to take strong notice and not only buy crypto, but to start to market it as a competitive advantage for themselves and clients.
Many of these buys at first will be via OTC markets, but folks... mark my words, these are drying up (I mean, JUST Greyscale is buying ALL the BTC that is being mined with great regularity now), and when they do, these guys will have to start market buying from exchanges. :-O . Oh, and then perhaps... just perhaps, companies like:
...start buying crypto as part of their reserves. .
Suddenly a $5-10Trillion total crypto market cap doesn’t sound so crazy. Have a fine day.
