Cheers mate, well met!
First of all - good luck for the tournament! Awesome that you’re representing Chaos Dwarfs there, way to go.
So I’m not familiar with this COMP value?! How is that calculated and what does it mean?
Obviously you’re playing the Legion of Azgorh list, but just to make sure: you do, don’t you? 
From these two lists I prefer the first one. Personally I love me a Sorcerer-Prophet on Great Taurus, but in a competitive setting he’ll just be a giant target. I’d run him on foot, like you do in the first list.
But I have some questions/comments about the first list:
- The Sorc-Proph and the BSB go in the Infernal Guard unit, yes? This will also be the juiciest of targets then
But also quite powerful, I give you that.
- What is your battle plan with the Bulls? They are super tough, especially with the Shields, but only have 6 attacks total plus stomp, all only at S4. So don’t count on them to kill much, they are a mobile anvil, not a mobile hammer.
- I wouldn’t give the Razor standard on the Infernal Guard. Sure armour piercing is nice, but they already have -3 armour save modifier and it costs a whooping 45 points. Banner of Swiftness (like in the other list) is better IMHO, or even no magic banner at all. Depending on your battle plan you might also consider the banner of slavery
- How about the Potion of Speed for your BSB instead of the Ironcurse Icon? 6+ Ward Save is well, only a 6+, but that +3 Ini might just be the thing tipping the scales in that one round of combat where you have successfully cast Ash Storm on a target and your BSB swings the Black Hammer of Hashut.
When I add up your lists I come 10points short, btw. Dreadquake + Ogre and Destroyer are only 540pts and the core is only 941, so maybe there Is even more wiggle room.
This is how I would tweak the list:
- Hobgoblins only with bows and no standard
- add a Daemonsmith (dispel scroll caddy and can help the Dreadquake)
- ditch one Khan and get 5 Wolf Raiders instead. No magic items on the Khan
- get necessary points by decreasing Infernal Guard
It could look something like this. Still with a nice 35 model Infernal Guard unit (great 7x5 formation. Or still as a horde for even more attacks!)

Alternatively one could decrease those Infernal Guard by further 7 models (for the 7x4 formation), give all Hobgoblins Shields for more endurance, the Bull Centaurs get a Ba’hal for that one extra attack and some magic banners get switched around.
