Not according to the GNU Coding Standards:
http://www.gnu.org/prep/standards/standards.html#Command_002dLine-Interfaces

"--version
This option should direct the program to print information about its name, 
version, origin and legal status, all on standard output, and then exit 
successfully. Other options and arguments should be ignored once this is seen, 
and the program should not perform its normal function."

In other words, typing --help after --version is too late; parsing --version 
should quit the parser.

And for precedence, none of the coreutils behave in the manner of hello 2.1.93; 
they all treat whichever option of --version or --help that appeared first as 
the winning option.
