the hlists and vlists have

glue_order 
glue_set
glue_sign

I am guessing that you only have to multiply list.glue_set with the data stored in the glue_spec nodes of that list (spec.width) if the list.glue_order is equal to the spec.*_order in the glue_spec node. The other cases are left to you as an exercise :)
