The security of this kind of system is delusional if you key in HOUSE, which is equivalent to 46873, because you may as well set it as 34678 which is hardly a secure combination. This is a major drawback of any mechanical keyhides such as your mechanical designs.
as with all mechanical combination locks, the order won't make a difference. The lock has no way of knowing this. But that doesn't mean it's completely insecure. It is a lower security type of locking device.
