How to make a new-defined alphabetic sort order in a locale work?

I'm working on a new Latin-based script for Persian. So I've used such lines in GB locale file, to modify the sort order:

First of all, I've introduced the new characters in such way:

collating-symbol <acirc>

Then, defined the order:

reorder-after <a> <acirc>

And, finally the unicode:

reorder-after <U0041> <U00C2> <acirc>;<CIR>;<CAP>;IGNORE % Â

But, after I save the file, and run the command sudo dpkg-reconfigure locales, nothing is changed, and the applications such as Text Editor or LibreOffice Writer don't obbey the new-defined order.

Should I do more to introduce this new sort order to apps?
