I found out that you can use skills_to_gain to add perk points in a specific perk. I still don't know yet how to add general skill points outside of quests, but this should be very useful. Seems to require the Class GainSkill.
Code:
<property class="Action0">
<property name="Class" value="GainSkill"/>
<property name="Skills_to_gain" value="perkHeadshot"/>
</property>
