Hi Scampi,
I'd be pretty outraged by that. I'm very careful with phrasing and choice of words when responding to any NC, and in these modern times where our audit reports are routinely shared with customers I feel that the response we have given is important as it is directly considered as part of our customers' assessments of us as a supplier.
The pragmatist in me wants to say "never mind, the audit was signed off", but in reality I'd definitely challenge it with the CB - they're clearly happy with the content of your CAs as they've signed it off, so why the need to reword them?
Initially I'd make an innocent "has someone accidentally copied some text on top of our responses; can this be corrected please?" enquiry with them - I strongly suspect that is likely to get it fixed, otherwise it'd be time to raise a formal complaint.
The thing that some CBs seem to forget is that many standards require food businesses to assess their service providers and review their performance, and CBs are a service provider just like any other...
If you really want to wind them up you could send them a formal NC notice, but tempting though that could be I think it may make for an easier life not to do so 
If the innocent enquiry followed by a complaint route doesn't work then you could always try raising with the scheme owner directly - IMO they should be quite concerned that their CBs are bordering on misrepresenting information. If nothing else, it needs to be consistent with what's happened in reality as it's likely to be an area that the next auditor will focus on (certainly with BRC they pick up on the previous NCs in detail), and a new auditor will be reliant on the report so if what you present on site doesn't align with this they're going to conclude the peculiarity is at your end, which seems grossly unreasonable.
