Hi,

Can somebody please share with me what the hierarchy of the data is (for layers)? I've tried to take a look at the data myself, but would be great to see if there are a set of rules in place.

For example - it looks like bridges which are of a height >50m are always assumed to be layer 5. What are the rules for this?

Can you describe your problem in a bit more detail? It may be that we don't understand what you're trying to ask.

There are no rules about the drawing order if that's what you mean; every map style has to decide for themselves what they want to do. The layer tag is used to model a local layering but the 50-meter-bridge rule you mention is not a general rule, just something someone has made up for their particular map style.
