Would really love to see Opera support multiple profiles within a single OS Desktop log in. Something akin to the Firefox profile management system which allows for creating multiple profiles and launching a specific profile via AppleScript Application Bundle, not the Chrome system, which really sucks in so many ways.
You could use Opera, Opera beta, and Opera developer. All three uses separate profiles. That would be the easiest, I think. You can use command line switches and alias shortcuts, but it gets complicated very fast.

Since the OP likes to use AppleScript he can probably handle it.
You could use the
--user-data-dir=switch to Opera to use an alternative profile directory, e.g.:
do shell script "open -a /Applications/Opera.app --args --user-data-dir=$HOME/Library/Application\\ Support/opera_alternative_profile"
Just change the last part (
opera_alternative_profile) to whatever you consider to be suitable.
