The idea is good, but I don't think the implementation is appropriate
in general.  Further, I don't like the option's name.  Ideally, gpg
would iterate over all of the PK-ESK blocks, determine whether the
user could potentially decrypt them, and then rank them according to
the expected ease with which the user could do that.  One criteria
would be the one that you suggested.  That idea has been floated
around in the past and will hopefully be implemented in 2.3.

Thanks!
