-Remember, because of policy set forth by the +IsStandard()+ function at the time of this writing, standard multisignature scripts are limited to at most 3 listed public keys, while P2SH are limited to at most 15 listed public keys. Standard multisignature scripts can invalidate transactions by way of their locking +or+ unlocking script, while P2SH can invalidate transactions by way of their unlocking script +only+. This is because there is no way for +IsStandard()+ to tell if a hash of a redeem script in a locking script includes more signatures than the currently imposed size limitation, so it can only observe the unlocking scripts in transaction inputs.
