Matching - Answers in HTML

Hello, this is my first post ever on Drupal.org, but I respect open source a lot. Hence I'm trying to be as helpful as I can i.e. not being a leech. With that out of the way...

If a tech savvy user reveals to see the code they can easily figure out the answers to all matching questions.
Take a look at the following sample image.

Under the HTML for the drop down (the box section with the arrow to be precise) you get something like this (for the sample in the image above):

<select id="edit-tries-5" name="tries[5]" class="form-select">

<option value="def"></option>
<option value="2">OPTION A</option>
<option value="3">OPTION B</option>
<option value="1">OPTION C</option>
<option value="5">OPTION D</option>
<option value="4">OPTION E</option>

</select>

The user can then see that OPTION D, is tagged with the same value as the as the drop down's name and id.

In the theming file of matching (mathching.theme.inc) I found the following at line 34:

/**
 * Theme the answering form
 */
function theme_matching_subquestion_form($variables) {
  $form = $variables['form'];
  $out = '<table class = "matching-tbl">';
  foreach ($form as $key => $value) {
    if (is_int($key)) {
      $out .= '<tr><td class = "matching-question">' . $value['#question'];
      $out .= '</td><td class = "matching-select">' . drupal_render_children($value) . '</td></tr>';
    }
  }
  $out .= '</table>';
  return $out;
}

The HTML code from before is rendered under drupal_render_children($value). I'm having trouble further figuring out where this $value is coming from and what it's doing. I've worked on it for about an hour. I will post updates to this thread. If someone that is more PHP/Drupal savvy wants to help, you are welcome to.

P.S. I tagged the bug as major because users who depend on this module can easily have their tests cheated on with one whistleblower. Feel free to change the priority if you feel I did wrong.
