As you've noticed yourself, gliscor causes you grief. This will also happen with pretty much anything that calls itself a physical tank or wall- three physical sweepers is utterly redundant. A battle tower team really wants a physical sweeper, a special sweeper and a mixed sweeper to cover all bases. You could either do that with your current team by going to these pages:
www.smogon.com/dp/pokemon/salamence
www.smogon.com/dp/pokemon/tyranitar
Use the salamence moveset called specsmence (Special sweeper) and the tyranitar set called tyraniboah (Mixed sweeper), with scizor being the physical one. Alternatively you may wish to bring in new members, ask me if you want any movesets. As for your current ones:
*The only move on that salamence set you should be using is outrage. Zen Headbutt has almost zero coverage and the fang moves are awefully weak. Outrage is your primary attack and is only resisted by steel types, so the rest of the moveset should aim at removing them. Earthquake is the staple move for this purpose, removing the vast majority with its high base power. For the two that avoid the first two moves (Bronzong and Skarmory, although shedinja also falls into this category but isn't really a problem), use fire blast rather than fire fang. Fire blast's high base power makes up for using it on mence's inferior attacking stat, and also hits skarmory on its SpDef which will hurt a lot more. Aqua Tail for the final slot to nail palmer's hippowdon and the likes of gliscor.
*Consider either dragon dance or curse over earthquake on tyranitar, as he is a menace with a few boosts behind him. Earthquake is only needed for the same reasons as salamence (Killing steels), which aqua tail already does on this set and has better neutral coverage. Your current EV spread is fine for a curse TTar, but a DD variant will want 252Att/252Spd@Jolly, while leaving your set as it is wants 176HP/252Att/80Spd
*Roost or Swords Dance over ariel ace on scizor- it's coverage is redundant and not real worthy of a moveset without STAB. Scizor is pretty bulk for a sweeper (Those HP EVs are slightly pointless btw, just run max speed)
But yeah, those are how the sets should look, but not how the team should. Make the changes I've suggested and you should do a bit better.
