That can't work with configobj. Think about this example:

c = ConfigObj()
c['one'] = 'one'
c['section'] = {}
c['two'] = 'two'

When ConfigObj writes out the file it does this:

 >>> for line in c.write():
...  print line
...
one = one
two = two
[section]

You seem to want it to do this:
one = one
[section]
two = two

The problem is that the key 'two' is now *inside* 'section' - it's in 
the wrong place and when reading the file back in it would do the wrong 
thing. Scalars *have* to be written out before sections.

All the best,

Michael
