Ruby, Python and Perl are older than you probably realize. Ruby started in 1993, Python in 1991, and Perl in 1987. I would not worry about their long term prospects: they've been around for a while, and I think it's a safe assumption they will be around for a while still.
Avoid decision paralysis. If you like Ruby, go with it. As I said, I don't think which scripting language you pick is all that important, but I think it's crucial that you know one.
