It looks like support for this was added in a few weeks ago, however, it looks like there's a slight issue: if the check is successful, it adds another regular attack instead of the special attack used. Here's the current code:

   80 		if(max_damage > 0 && GetClass() == MONK && skill != THROWING)
   81 		{
   82 			int specl = GetAA(aaTechniqueofMasterWu) * 20;
   83 			if(specl == 100 || specl >= MakeRandomInt(0,100))
   84 			{
   85 				Attack(who);
   86 				if(20 > MakeRandomInt(0,100))
   87 					Attack(who);
   88 			}
   89 		}

If it's changed to this:

	if(max_damage > 0 && GetClass() == MONK && skill != THROWING)
	{
		int specl = GetAA(aaTechniqueofMasterWu) * 20;
		if(specl == 100 || specl >= MakeRandomInt(0,100))
		{
			who->Damage(this, max_damage, SPELL_UNKNOWN, skill, false);
			if(20 > MakeRandomInt(0,100))
				who->Damage(this, max_damage, SPELL_UNKNOWN, skill, false);
		}
	}

that should trigger the additional 1-2 special attacks (flying kick, etc).
