bonus skill ranks from trait

[psych777]

have a trait that gives bonus skill ranks:
You gain bonus ranks in Profession (sailor) equal to your character level and it is considered a class skill.

originally i built the script to add bonus equal to the char level but then a groupmate pointed out it is bonus ranks, not just a bonus, so that its basically a free skill as i get a rank per level and i can't exceed ranks beyond char level. so i'm relooking at my script and trying to determine the best field to use.
if i use skItem or skInnate then the skill matrix gives the right amount of ranks plus adds the Class skill bonus AND if i try to add a rank using the arrows it flags the skill red (as invalid). the other fields either didn't add the class bonus or didn't flag it invalid if i added ranks.
i assume i should stay away from skItem as items use it. is there any reason i shouldn't use skInnate (Innate Skill Ranks)? and if i shouldn't, what field should i use to get the class bonus and flag the invalid if i try to manually add a rank?
using the following script:

hero.childfound[skProfSail].field[skInnate].value += hero.child[Totals].field[tLevel].value

~Profession (sailor) is always a class skill
#makeclassskill[skProfSail]

skInnate is for the pre-assigned skill ranks on a monster - those are charged against the character's total skill points.

Why not use skItem? This sounds like game-mechanics-wise, a lot like the bonus ranks from a headband of vast INT.

Headband of mental superiority +2 give free "ranks" in a selected skill equal to character level. Take a look at its script to get an idea for timing and fields to use.

headband of mental superiority adds a skill just like the headband of vast int (which is the one i looked at when trying to figure it out). they both use the skItem so sounds like i'll just use that one as well. thanks!
