No, Guns skills are not civilised. They are just applied hand-eye co-ordination when it comes to attacking someone, with maybe a bit of ballistics thrown in. Certainly no more civilised than Throwing.

More importantly, the only skills banned are those that "rely on 'civilized' notions of art or social interaction". Guns relies on neither civilised art, nor civilised social interaction, seeing as killing enemies/prey dead way pre-dates sapience, let alone civilisation.

Note it's not a ban on 'civilised skills', 'art skills', and 'social interaction skills'. It's a band on 'civilised art' and 'civilised social interaction' skills, which is a far more limited set of skills.
