The problem is definitely in the generated img and not how mapsource displays it. I would expect that both roads would be at resolution 22 which is probably not what you wanted but that is due to the usual issue of the action rules being run in an indeterminate order.
If you need to work around the problem while I look at it try this:
(highway=* | highway=primary) & maxspeed=40mph {set mcssl=40}

Both appear at the same resolution is wanted. What I was trying to achive was roads in different colours according to speed limit. However, I wanted more important roads to show at lower resolutions so you could zoom in and out easily and have a workable map. The problem lines were part of a much longer style file. Originally the file followed your work around, but this creates long style files because speed limits are defined in one of 5 ways on OSM data. The newer style file comes up with a consistent speed limit defintion first (mcssl) and then later on uses mcssl and highway type - at this point resolution for all primary highways should be 20, trunks 18, motorways 16 and other roads 22. This gives a much short style file. However, in testing I came across this curious bug that the highway key is lost for some roads if a name key exists. I can work around to get what I want but I guess at some point we need to find out why these particular combinations gets odd results.
