Looks like no one actually answered your question!
The geocaching map and most of the tools on Geocaching.com (and even here on Project GC) assume that a geocache has a variety of parameters. Geocache coordinates of course, but also country, difficulty, terrain, etc. Lab caches do have coordinates, but they are not assigned to a country, and many of the other parameters that a cache has (such as difficulty, terrain, favourites, DNF logs, and many more) are also not included.
Adventure labs are new, and pose a bit of a dilemma - an adventure lab is not a cache, it is a collection of caches (lab caches). The lab caches cannot be identified without the adventure lab wrapper. How should this be presented on the map? As individual caches? As the adventure lab? For now Geocaching chose to keep them off the main geocaching map.
However as noted elsewhere in this thread they may be added to the GC map sometime this year. Hooray!
