They don't purposefully avoid spikes.
Zombies don't acknowledge traps as anything but blocks to path on, or through. To them it's all either a wall, or open space.
What they DO do, however, Is avoid walls when there's a perfectly viable alternative. And they also prefer taking the least block-HP path to the player.
So, When you make a 1 tall row of spikes, Zombies consider it to be a low fence, and will probably jump on it. When you make it 2 tall, however, You've built a solid wall- At least in their eyes.
When you've made a row of spikes 2 blocks tall, The first couple zombies will stumble into spikes, and then once a sufficient opening has been made, The rest will path to that opening because it is now the lowest-block-HP path to the player-To them, any other path that would take them into the 'wall' takes longer, and thereby, is not worth going to.
So basically, Don't just build a solid wall of spikes. You need to place them on the floor- Even better, place them set 1 or 2 tiles into the ground so the zombies consider the spikes to be 'floor' and will walk right onto it.
