How to copy contents of Node title to a CCK field?

I'm trying to get the content of the Node title (node.title) of one content type into a CCK field (content_field_title.field_title_value, I guess) in the same content type (and then strip a pattern from the title, but that's a different issue).

After looking into the CCK database tables I don't think that I can manage to do this with a simple INSERT/UPDATE SQL statement. So I was hoping that something like this might be into the scope of the VBO module.

In #852020: How to copy contents of Body field to CCK field? a similar issue was discussed; to get the node's body into a field, this statement was suggested:

return array(
  0 => array('value' => $node->body, 'format' => $node->format),
);

As a non coder I'd guess that the I'd need $node->title, but neither node titles nor my target CCK field accepts a format. So maybe I would end with something like this?

return array(
  0 => array('value' => $node->title),
);

Where would I enter this in VBO (probably action "Execute arbitrary PHP script")?

After reading #729962: Copy data in CCK field to Body field I tried this PHP snippet which didn't work for me:

$object->title = $object->field_title[0]['value'];
node_save($object);

So I'm pretty stuck with this. A generic action to copy and/or move content between fields for non coders would be a really great addition to VBO! Something like Field Copy, but with support for Drupal core "fields" like title and body...
