Try to read and understand the last post again. Read up on difference between "recover database" and "recover database using backup controlfile" for starters.
One last time -
The new controlfile is aware of SCNs from 3 days ago. After you recover the entire database to 'sysdate-3' (or whatever), it is a question of "forward recovery". (That's the whole concept of "recover database using backup controlfile" - it's kinda the same thing with "create controlfile" and recovery as well. )
Once you're "forward recovering", it is just a question of asking for incremental sequence numbers.
Sorry, this is the best that I can do. Others, feel free to elucidate.
