due to an "error in design", there is no way to achieve this, especially in a multi-language environment.
[You would have to install wb again, and to patch the core. -- Then, it may work as expected (depends on installed modules) -- totally untested]
As workaround you may use a temporary DB-table to sort the results (not allowed by some Providers),
or use sort with SORT_LOCALE_STRING and setlocale() (some providers forbid the use of sort on large arrays).
