There is a 1-confirmation attack on old implementations, but it is expensive and difficult in practice. The attack is:
# Attacker creates a pay-to-script-hash transaction that is valid as seen by old software, but invalid for new implementation, and sends themselves some coins using it.
# Attacker also creates a standard transaction that spends the pay-to-script transaction, and pays the victim who is running old software.
# Attacker also creates a standard transaction that spends the pay-to-script-hash transaction, and pays the victim who is running old software.
# Attacker mines a block that contains both transactions.
If the victim accepts the 1-confirmation payment, then the attacker wins because both transactions will be invalidated when the rest of the network overwrites the attacker's invalid block.
