The $key parameter will be a key of returned children array. For example, if you have:

1 -> fruit
12 -> apples
13 ->  bananas

taxonomy_get_children(1, $vid, 'tid') will return:

<?php
$children = array('12' => $termobject, '13' => $termobject2);
?>

taxonomy_get_children(1, $vid, 'name') will return:

<?php
$children = array('apples' => $termobject, 'bananas' => $termobject2);
?>
