Just to play the devil's advocate here. This could be a problem if we
still remember the story of bones ...

For one thing, we cannot assume that C, J, K agree with a single set of
radicals, let alone their ordering: sorting is a very cultural thing
and an agreement is harder to get than assigning a character to a code
point in 10646. This leads me to my next point: it might be useful to
allow multiple-level of defaults (or graduated tailoring, depending on
how you look at it). 14651's default is the first level, where CJK
characters could be simply sorted by thier order in 10646 (or some
compromise if someone's willing to try); the second level could be tied
with a National Profile. If it happens to agree with 14651's first level
default, great; if not, that's usu a problem within a single culture
which would be easier to deal with. User-level tailoring would happen
below the National Profile level.

In the spirit of co-operation, maybe IRG could identify differences in
radical/count sorting within cultures using CJK characaters and try to
resolve "minor" differences (agreeing with an order).
