Jason Scott must have been involved with Silent Threat though, because he voices his namesake Admiral Scott in the briefings.
You should probably be able to hit at least 120 in a blank scene with no action, though...
Speaking about Corinthos/Trebuchets - Does EA have any analogue to it?
The EA has the Halberd (I believe that's what it's called), but it's not used in R1. In R2 it will murder you, as it's basically a treb combined with an Infyrno and also has kinetic/pushback effects.
So the AI can't ever fire the trebuchet. However with FuryAI this problem can be fixed using the "Smart secondary weapon selection" flag, this is what BP uses to get its AI to fire trebs(and you'll have to dodge quite a few of those in WiH).
You can change the retail AI_profiles table to let AI use trebs in FS2, however this totally breaks the game. Maras and Basilisks carry trebuchets by default and their loadouts are very rarely edited so you'll be dealing with massive trebuchet storms as soon as the Shivans show up.
