Tabe titles on user/{,register,password} pages

It seems that when you change the text for the login block links, it cascades that change for the 'create account' link but not for the 'new password' link; I'm trying to effectively swap the two over, and this works fine for the login block, as I can override the targets of the links with each other's urls, and similarly swap the text (although I also alter one of the). However, it leaves the tabs at the top of all three pages confusing, as I have two tabs that say 'Forgotten password?', one of which points to the 'create account' page.

Looking at the code, I see that there's a block that applies to the page version:

      if (!$inpage) {
        $items = array();
        if (variable_get('user_register', 1)) {
          if ($register_button) {
            // Add a new register button ...
            $form['#validate'][] = '_itweak_login_custom_buttons';
            $form['register'] = array(
              '#type' => 'submit',
              // Place at the same weight as "Login" button for now
              '#weight' => $form['submit']['#weight'], 
              '#value' => $register_button_name,
            );
          }
          else {
            // ... instead of a regular link
            $items[] = l($register_name, $register_url, array('attributes' => array('title' => t('Create a new user account.')))); // HERE
          }
        }
        if ($recover_button) {
          // Add a new register button ...
          $form['#validate'][] = '_itweak_login_custom_buttons';
          $form['recover'] = array(
            '#type' => 'submit',
            // Place at the same weight as "Login" button for now
            '#weight' => $form['submit']['#weight'], 
            '#value' => $recover_button_name,
          );
        }
        else {
          // ... instead of a regular link
          $items[] = l($passwd_recover_name, $passwd_recover_url, array('attributes' => array('title' => t('Request new password via e-mail.')))); // HERE
        }
        $form['links']['#value'] = theme('item_list', $items);
        // Fix unassigned weight (it breaks order of controls later on)
        $form['links']['#weight'] = $form['submit']['#weight'] + 1;
      }

The lines labled HERE are those I assume apply the changes to the tabs. I can't see why one would be working but the other not. Of course, the text on the tab that's wrong isn't the default value in the code for passwd_recover_name either, so I'm at a bit of a loss.

Otherwise looking at what might be the problem, I can't see anything being done for the password recovering page but not the registration page. This may end up being a game-breaker, so I'm hoping for some guidance or help. I can think of several hypothetical explanations, but none that would be asymmetric like this.
