Arrange search using array

I have a problem, I did a search system by tags, I calculate the percentage of the search by how many tags have the result by how many equal tags (example: 10 tags of the result, 5 equal, or 50%). However I need to sort the results and it is not possible with ORDER BY (since it is not in a column), so I came across a system to sort via array, but since there are multiple results generated inside a foreach, several arrays are created and not a single one to be able to sort. If someone can select or give an easier way I am grateful.

* NOTE: I would use "sort" to organize * OBS2: I'm using PDO

<?php  
            $palavra_buscada = $_GET['search'];
            $palavra1 = array(', ');
            $palavra2 = array(',');
            $palavra1 = str_replace($palavra1, $palavra2, $palavra_buscada);
            $palavras = explode(",", $palavra_buscada);
            for ($i = 0; $i < count($palavras); $i++) {
            $queryLike[] = "name LIKE '%" . $palavras[$i] . "%' OR tags LIKE '%" . $palavras[$i] . "%' ";
            $where = "" . implode(" OR ", $queryLike) . "";
            $total = "SELECT * FROM videos WHERE " . $where. "";
            $totalizando = $conn->prepare($total);
            $totalizando->execute();



            }

                $count_pesquisa = $totalizando->rowCount();
            ?>
    <div class="listTop"><span>Videos encontrados<span class="videos-f"><?php echo $count_pesquisa; ?></span></span></div>
            <?php

                if($count_pesquisa > 0) {
                    $result_pesquisa = $totalizando->fetchAll();
                    foreach($result_pesquisa as $row_pesquisa) {
                        $video_name = $row_pesquisa['name'];
                        $tag_name = $row_pesquisa['tags'];
                        $tag_explode = explode(",", $tag_name);
                        $tag_count = count($tag_explode) - 1;
                        $result = array_diff( $tag_explode, $palavras );
                        $tag_equal = count($result) - 1;
                        $total2 = $tag_count - $tag_equal;
                        $percent = round($total2 * 100 / $tag_count, 1);


                        $percent_a = array(''.$percent.'' );
                        print_r($percent_a);
                        rsort($percent_a);


                            foreach ($percent_a as $tchau) {
                            echo '      
                            <h1>'.$video_name.'</h1>
                            '.$total2.'/'.$tag_cont.'<br>
                            Porcentagem'.$tchau.'

                        ';
                            }
                            echo '<br>'; 








                        echo '
