I've never used skulltag so I'm not totally sure about this, but having that it's based on Zdoom I hope it works.

First of all I haven't completly understood when do you want your waves to stop, and how exactly you've builded them. Are them teleports? Closets? Spawns using ACS? 

In order to open the doors you have to give to each monster of the last wave a tag and then write a code to check if all of them are dead. An example follows 


script 1 ENTER


       while (ThingCount (T_NONE, 1) > 0)

                  Delay (35);

       Door_open (1, 64, 0);



This script will loop in the while command until all the monsters with tag 1 are dead (and this is checked once per second, according to the delay). Then, the doors tagged with 1 are opened at the speed of 64.

Here you can find informations about ACS functions


Complete list of ACS functions:



ACS action specials:

In other words how to use the normal linedefs action in your scripts



Skulltag specific ACS functions:




As long as you don't provide the method your waves work I can't be more specific I'm sorry
