Take a closer look at your scripts you posted. Even the one you posted that you said works, would not actually work.

sub EVENT_SPAWN
{
	quest::settimer("woodcut",1);
}
sub EVENT_TIMER
{
	if ($timer eq "mine")
	{
		# Random Animations: 2h slash and 1h slash
		my $anivar1=quest::ChooseRandom(3,5);
		quest::doanim($anivar1);
		quest::settimer("woodcut",3);
	}
}
sub EVENT_SAY 
{
	if($text=~/Hail/)
	{
		quest::emote("appears to be dripping in sweat as they chip away at large chunks of ore and crystal");
		quest::say("I don't mean to be rude but go away. There is enough work to do here without some outsider wasting our precious daylight.");
	}
}

You need to check for the same timer name in EVENT_TIMER that you set the timer as in EVENT_SPAWN.

Other than that, your 2 random timer scripts look fine.
