For much better results i actually recommend implementing this third party library through Composer https://github.com/wyndow/fuzzywuzzy
The code would look like this.

use FuzzyWuzzy\Fuzz;      
$fuzz = new Fuzz();

usort($results, function ($a, $b) use ($query, $fuzz) {
   $a_label = is_array($a['label']) ? $a['label']['label'] : $a['label'];
   $b_label = is_array($b['label']) ? $b['label']['label'] : $b['label'];

   $percent_a = $fuzz->tokenSetRatio($query, $a_label);
   $percent_b = $fuzz->tokenSetRatio($query, $b_label);

   return $percent_a === $percent_b ? 0 : ($percent_a > $percent_b ? -1 : 1);
});
