In this case I would prefer not to have to cast at all, thus
where ( p instanceof Cheque and p.paperType = :paperType) or (p instanceof CreditCard and p.pinCode)
should be enough.
And if one write
where p.paperType = :paperType
and p isnt of type Cheque (or to be more concrete, do not have a property named paperType) simply throw a PropertyNotFound exception.
