Hi,
you have to escape characters with regexp meaning (see docs for details).
Try this:
email matches "@\[A-Za-z0-9\]*"
phone not matches "\\\\d{3}\\\\-\\\\d{3}\\\\-\\\\d{4}"
Moreover I guess your rule is anyway broken, you will get a cross
product of Orders, so I would remove "There is an Order" from both rules.
Cheers,
Jarek
