How can I make a stroke look pixellated like this in Photoshop CS6?
I'm talking about the sign's border specifically (not the text). Ideally I don't want to have to manually draw the pixels, so it's repeatable at different sizes.

After a fair amount of fussing around with slight tweaks here and there, I was able to achieve something similar, using
36 Pixels/Inch for the image resolution.
I think there is a sweet spot between
29 - 40 PPI that will provide the best results, but I don't have all day to experiment.
The slightly tricky bit is if you want to start it as a larger image. I created it with exactly the number of pixels I could count on the actual object which was
25 x 198, it allowed me to apply a
1px Stroke to match what I can see in your example. Now, if you wanted to create it at three times the size, you would have to triple the stroke size to.
That's why I recommend creating it with the exact amount of pixels and scaling up when you save.
There are repeatable ways to achieve this, but no matter what, if you want exactly those results in your example, it will take a fair bit of tweaking.
Anti-Aliasing where you can, on the type specifically, makes it far more possible. I used Arial, and after trying various transformations, I'm fairly certain it isn't Arial in your picture. It's definitely easier to use a purposefully pixelated font as Scott suggests.
You can then scale it up when saving, make sure to use the
Nearest Neighbour quality option otherwise it will apply a lot of anti-aliasing.
Also, the gradient appears to be custom made.
As per the method in the very similar question linked to this one, using a
Drop-Shadow and adjusting the
Contour achieves a better effect than the stroke, using the settings you can see in this screenshot:
This is the final result using the drop-shadow method:
If you look closely at the corners, the drop shadow method achieves tighter, thinner corners with less aliasing.
You will have to draw the edges that way, or find a pixel font without any anti-aliasing (for the text).

For the stroke....
It's really a simple matter to grab the Rectangle Shape Tool, tick the Align Edges option on the Control Bar and set the Shape Mode to Combine, then zoom in and draw rectangles. It only takes a few moments.....
And once you do this you can enlarge all you want and retain the edges....
In addition, you can use
Edit > Define Custom Shape... to save this shape and reuse it later easily. Like all vector shapes, There's no worry about ppi of the image, layer styles, anti-aliasing... or really any of the other inherent issues with pixels if you utilize vector layers this way. The vector layer will work on any image regardless of resolution, color mode, etc.
