[RMVX ACE] SKILL LIST ORDER IN MENU. PICTURES INCLUDED!

In this game I'm working on, all of the characters' skills are based off of their equipment. Each character is able to equip a main-hand weapon, an off-hand weapon or item, and a spell ring. Main-hand weapons consist of 3 skills each, off-hand weapons and items have 2 skills, and spell rings have 1 each, but up to four spell rings can be equipped at once. Players will be able to swap all of these things at will.

So what I'm trying to do, is to come up with a way to sort the skills that the player has. I want the Main-hand skills first, then Off-hand skills, then Spell ring skills. I'd like to try and find a solution that separates the order of these skills by tiers.

Take, for example, my heroine Elsa. She's been prancing about killing enemies with her trusty sword and shield. But... she soon is going to get her hands on a shiny new THUNDER SWORD which, when equipped, will allow her to harness the SWEET POWER OF THUNDER.

So this is how she looks like at the start.



Our hero Elsa has her trusty sword and shield equipped. The sword skills are first, followed by her shield skills. No spell rings equipped at the moment. But it looks great! Everything has been working well like this, so far.



Here's her equipment. Looking sharp! However... I just found this sweet new THUNDER SWORD, and I want her to put it on.



Okay that should be just fine. Ignore the fact that it doesn't properly give 4 attack, I'm still tweaking it...
So she equips the new weapon, AAAAND...



Look at that. Now the order of skills are all messed up.

I think this kinda' tells you what I'm getting at. Maybe there's a super-easy solution I'm missing, or a tiny script that makes this not-so-hard, but yeah. In the words of our hero Elsa, "please help."

Wow, that... is totally what I need to do. Thank you very much!

Now I can properly harness the power of thunder, in proper order. Please excuse me as I go throw things while adjusting my entire database.

(Thanks again!)
