That's startling. I don't have a modern (windows 7 or later) platform available to test on, but given that all the locales ids are different there should be no imaginable way for a new locale version to affect the order of these collations; the only thing I can thionk of is that some locale ids have been changed.

It would be useful if you could run the following code and post the results here, so that we can see what has happened in Denali to make this order change.

select cname CollationName, collationproperty(cname,'LCID') LCID

from (values('bosnian_latin_100_ci_as'),

('corsican_100_ci_as'),

('latin1_general_100_ci_as'),

('norwegian_100_ci_as'),

('romansh_100_ci_as')

) X(cname)
