I never played with "scripted" NPC actions because usually it's not a good idea replace the internal AI actions with any kind of scripted behavior (it will mess the AI action). But anyway, I think it's not possible make the NPC walk and cast spells at the same time because to make it walk you need to set ACTP and start action 074 ("runningto") and to make it cast spells you must set ACTPRV, ACTARG1 and start action 25 ("skill_magery"), so one action will override the other. Even if you call ATTACK function it will probably also override the previous action

long story short: NPC AI can't handle 2 actions at the same time
