Has anyone tried relabelling the phone number? I have, and the message delivery system used changed according to the label of the number sent to.

PuririDowns - those labels are purely decorative and have nothing to do with the function of the phone. It's like labelling a number "work" versus "home" - it's only for your benefit, the phone treats them exactly the same.
When the phone number I send to is on the "Mobile" field, then new messages are sent using the SMS delivery system. When that same phone number is re-labelled as "iPhone", the iMasseage delivery system is used. You can tell which delivery system the phone is intending to use by the label in the message box - it reads either "message" or "iMessage". That decision intelligence can only come from the phone itself.
I also experimented with switching off "mobile data" and "WiFi". New messages were sent using SMS.
There is a point of confusion though. Now that I have both iMessage and SMS messages to the same recipient, I have 2 different and separate message streams and can continue to reply to messages in each stream using the different delivery systems.
It seems to me that, in hindsight and coming from experimentation, Apple's logic in designing iMessage is correct but confusing until we know how it works. Apple are very poor at explaining the hows and whys of their services. I would prefer that Apple do not 'dumb down' their services and instead disclose how and why things work for those of us that want to know.
In Apple's product documents, they do make the point very clearly, about what to do when transferring a sim card or phone number to another non-iphone:
"If you plan on transferring your SIM card or phone number from an iPhone to a device that does not support iMessage, turn off iMessage in Settings > Messages first. If you do not, other iOS devices may continue to try to send a message using iMessage first, instead only using SMS or MMS."
