In 2.0 this is correct.  The terrain ordering is hard-coded in the map 
generator.  You can change the terrains around but the generator will 
not work (you'll have to use scenarios).

In the development version (2.1) this is improved.  The terrain ordering 
is no longer hard-coded and you can change terrains around as you want. 
  For instance you can add deep-sea and coastal-ocean terrains.  The map 
generator does the best it can given certain parameters you can edit for 
each terrain type in the ruleset.
