As has been mentioned the order shouldn't matter but there is a way to manage
this using the smime utility or the cms utility in some versions of OpenSSL.

If you use the option -nocerts the signing certificate will not be
automatically added to the output. You can then include the signing
certificate in the -certfile option in whatever position you want. This
functionality was added to some versions of OpenSSL to workaround this
problem where some implementations depend on the order.

Whether this works in practice for the smime utility will depend on the
version of OpenSSL: some versions interpret -nocerts to exclude all
certificates so you get none at all in the output. For 1.0.2 and master
you should be fine. 

If you use the cms utility instead of smime it should work in any version of
OpenSSL.
