Ditto.
This is a classic example of a ratio IQ test (cognitive age/chronological age multiplied by 100), except that the material is totally jumbled and much of it is achievement rather than intelligence. I wouldn't take much or anything from it. The scores certainly would not correlate to modern tests.
As you said yourself, your child is too young for testing. It's a strange place to be in, knowing that your child is gifted and wondering how gifted and having no way to know. I am there too. Maybe all of us are there or have been there.
