In general I think it's better to use set instead of add. I don't know 
what happens if you use add display_name if display_name already exists.

I would use:

highway=* & maxspeed > 1 { set display_name='${ref} 
(${maxspeed})'|'${name} (${maxspeed})'|'(${maxspeed})' }

Btw: How does display_name work?
