Missing something simple

I created the following short test module to understand how paths work. This code is installed in /sites/all/modules/scoreos. When I go www.url.com/scoreos/test or www.url.com/scoreos/?q=test or www.url.com/?q=scoreos/test, they all send me to a 404 page. I'm sure there's something simple I'm missing but I don't see it yet. Any ideas? Thanks in advance.

      function scoreos_test_menu($may_cache) {
          $items = array();
      
          if ($may_cache) {
              $items[] = array(
                  'path' => 'scoreos/test',
                  'title' => t('Test'),
                  'callback' => 'scoreos_test_start_page',
                  'access' => TRUE
              );
          }
       
          return $items;
      }
       
      /**
       * Called when user goes to /?=test
       */
      function scoreos_test_start_page() {
          $output = t('This page contains our test.');

          return $output;
      }
