I am not sure where your system stands at current. It would seem to me that you followed the instructions perfectly as described in the Database Backup and Recovery Basics.
A few things to check.
1) Before you can do ALTER DATABASE OPEN READ ONLY, your database needs to be in a mounted state.
2) Have you tried to do ALTER DATABASE OPEN READ ONLY from a sql prompt and not from within RMAN (I know it sounds crazy but I have seen stranger things work.)
Lastly I don't think the documentation is correct. I really believe that you have to tell it to restore using a backup controlfile (even if it is the "current" controlfile) RECOVER DATABASE USING BACKUP CONTROLFILE. If you are using "RECOVER DATABASE" then RMAN is expecting the end of recovery marker. Well if you are doing a point in time recovery then you are doing and "incomplete" recovery and therefore it can not reach the recovery marker. I may be wrong but that is my view point.
