There is quite a long running poll at http://en.wikipedia.org/wiki/Wikipedia:Language_order_poll. Views on the English Wikipedia are fairly evenly split between "By order of alphabet, based on two letter code" and "By order of alphabet, based on local language".
I just added my vote for "By order of usage pattern in local language", i.e. I think they should be ordered by how people in each wikipedia language community actually use them. This may require some study of logfiles to see what people are clicking on.
But that's just one vote. :-)
