Alphabetization in Mythling Services Places Space Before Slash

This query in mysql:
select intid as id, filename
from videometadata
order by filename

sorts as follows:
id filename
89 deep/beyond deep 2/xxx.mpg
90 deep/beyond deep 3/xxx.mpg
91 deep/beyond deep/xxx.mpg

Figure out a way that the "beyond deep" directory will come before "beyond deep 2" or "beyond deep 3"
