I just found out if you wish to earn Steam achievements off these maps, move the map files to ..\My Documents\My Games\Sid Meier's Civilization V\Maps\
If you play a map from a mod Steam achievements are disabled.
I've been playing the TSL maps and getting acheivements. I go through the mod browser to load my games because I found that if you don't, other mods you activated don't seem to work (the clock widget).
Then again, I did not get the Magellan achievement when I circumnavigated the Earth!!!
