It's because both the U-wing and the Auzituck are fat crew carriers (A.K.A. Shuttles, though the auzituck is a little bit more than that due to wookie commandos and his 180), whereas the scurrg is a highly customizable multi-purpose combat ship, not unlike the millenium falcon. Comparing Scurrg to U-Wing is like comparing a Spitfire to a Boeing 747.
A Boeing 747 with a door gunner to be more accurate.
But seriously look at Rebel Nym and what he gets for 3 points more compared to Cassian. I think that's the real travesty here.
