Hmm, very topical for me.  I needed this just last week and came up with the
following script.  No guarantees on efficiency, but it does what I want.

Improvements gratefully accepted

obs = []

order_prefs = {'indoor':1, 'outdoor':2, 'pool':3, 'hlsm':4, 'classes':5,
'corporate':6, 'department':7}

def order_sort(ob1, ob2):
  try:
    return cmp(order_prefs[ob1.getId()], order_prefs[ob2.getId()])
  except KeyError:
    return 0

home = context.sport_root() # This is a custom script of mine that returns
the root of my site
for folder in home.objectValues(['Folder',]):
  if folder.hasProperty('inTopMenu'):
    obs.append(folder)

obs.sort(order_sort)

#put the sport site root object first
obs.insert(0, home)
return obs
