Unfortunatly I don't have Visual Studio, so I can't try in the target environment, but if it uses standard regexps, you could probably do it like this:
Search for "(:Al) = (:Al);", and replace with "\2 = \1". (\1 and \2 are references to the first and second capture groups, in this case the parenthesises around the \w:s)
EDIT
Ok, not \w... But according to MSDN, we can instead use :Al. Edited above to use that instead.
Also, from the MSDN page I gather that it should work, as the references seem to work as usual.
