Actually I think we already have some precedence for repeated options. 
See set.c:set_label(), and all the TBOOLEAN flags like set_position are 
handled: repetition of "strong" options is treated as an error:

gnuplot> set label 'text' at 1,2 at 3,4
                                  ^
          extraneous or contradicting arguments in label options

The difference in your current "set key" is that some options' effects 
are "weak", i.e. they only set a default for some other choice, which is 
expressly allowed to be overwritten by an explicit specification.
