as I stated before, there is no proper order; there are a few rules of thumb to keep in mind:
* some options can be specified only once; in this case the last option specified "wins". This applies to options like 'log', log-append', 'verb', most scripting related options
* some options can be specified multiple times; in that case the first one "wins" but the others are kept for backu; this applies mostly to 'remote' and '<connection>' blocks
Other than these caveats there is no order: it does not matter if you first specify 'ca' or 'cert' or 'key' or whatever.
