Why would you say that? If you look at the basics, the Scorpion has 2 engines and the Gripen has 1 - single engine CAS sometimes doesn't work out well (look at the F16 lost in December).
Other than that, I can't fathom why Scorpion wouldn't be able to survive. It would come into service with a functioning set of defensive aids and has a better rate of performance to an A-10. So if the A-10 can survive in that environment at 300-350kts, then why not Scorpion with another 50kts in hand?
