I have attached the results for Chez Scheme 8.3 (R6RS). I had to make some
basic modifications to the prelude, but I also had to change the test in
the macro (and res (nan? res) ...) to (and (real? res) (nan? res) ...)
because Chez Scheme's NAN? only accepts REAL? values.

There were 18 errors in total, all of them, as far as I can see, relating
to accepting prefix based numbers that the test says should error out. I'm
not sure I would argue that this is a bad thing.

Chez doesn't appear to have any errors related to the padding, but it does
exhibit the same flexibility that Racket has regarding these decimal
syntaxes.
