[_ck_]

It uses the action

do_action_ref_array( 'sort_tag_heat_map', array(&$counts) );

which looks like

function bb_sort_tag_heat_map( &$tag_counts ) {

uksort($tag_counts, 'strnatcasecmp');

}

So it was designed to be replaced fortunately.

First to have to unhook the existing action in your plugin:

remove_filter('sort_tag_heat_map', 'bb_sort_tag_heat_map');

Then put in your replacement

add_filter('sort_tag_heat_map', 'my_sort_tag_heat_map');



function my_sort_tag_heat_map( &$tag_counts ) {

// put your replacement code here

}

According to this, it’s supposed to support your locale, but there is a bug:
