This is true, but ddrescue uses Arg_parser and allows the options to be 
placed anywhere in the command line:

There is no way for ddrescue to take "--force" as the mapfile unless you 
precede it with "--" or type it as "./--force".

Ddrescue checks the command line before running it. Maybe you mean "--ask"?

--ask
    Ask for user confirmation before starting the copy. If the first
    letter of the answer is 'y', ddrescue starts copying. Else it exits
    with status 1.
    If they can be obtained, ddrescue shows the model and serial number
    of the input and output devices. Else it shows the size in bytes of
    the corresponding file or device.


AFAICT, this problem is just a lack of read permission on /dev/sdb3.
