? type([0][0]) = type(box(0))

In fact, this will print out "false".
The zero wrapped in an array has the type "roInteger" while the boxed zero has the type "roInt".
I am on firmware 7.5.

Here's what I use:

'======================== TYPE CHECKS =========================
' Apparently all of these are a lot faster than doing something like: IF Type(Th.spriteDraw) <> "roBoolean" ' or: IF Type(id) = "String" OR Type(id) = "roString"

    Return GetInterface(value, "ifInt") <> INVALID And (Type(value) = "roInt" Or Type(value) = "roInteger" Or Type(value) = "Integer")
End Function

End Function

So it does, it's a bug or a feature.
Don't check for type() = string, instead check getInterface(x, "roInt") <> invalid - will work for all kind of ints.
