The equals sign has no special significance to search engines. They don't care if you use an equals sign or a dash or any other legal character to separate parameter name from parameter value. Your problem, I think, is that you've been following some questionable advice right from the get-go.
What DOES matter is the order of the parameters. Any time the order changes you have a different "page," even if the content is the same. Ergo, duplicate content. But it sounds as if you already know that, as if you've already accounted for it. If, as you say, you'll enforce "strict order of the filter parameters" you should be good to go with your original use of the equals sign.Go to the full post
