After further investigation, it appears as though this affects the Live CD only. The alternate install works perfectly with RAID array creation even when Ubuntu is installed.

It appears as though the Live CD does not officially support software RAID array creation, see: https://help.ubuntu.com/community/Installation/SoftwareRAID#Requirements

Though this is not made apparent to the user when creating the RAID array (gnome-disk-utility is there and it allows you to get as far as configuring the array).
