The clause says deprecated and optional technologies will be banned. So sorry but if MacRuby is not part of the OS, then it is pretty clear it is optional so it will not be allowed on the appstore.
And it is completely useless to think about what makes sense or doesn't when talking about the appstore. The iOS app-store forbids apps that were made with particular compilers even if they are submitted in app-store allowed form. Does that make sense?

In such a liberal interpretation, all third party libraries could be banned, but no-one's going to entirely write apps that only use Apple's frameworks. That's not even the case with iOS. You can include extra "optional" frameworks into iOS apps no problem. The main reason MacRuby hasn't made it to iOS yet as an including framework is due to its reliance on garbage collection functionality not present in iOS.

I think you might have missed the update on that story from a month ago. Straight from Apple's mouth:
In particular, we are relaxing all restrictions on the
development tools used to create iOS apps, as long as the
resulting apps do not download any code.
