I must admit that I both (a) have scripts that were written for Perl 4 in personal production (i.e., I'm the the only user), and (b) that I still code most in Perl 5 more than any other language (not that I write much code anymore, sadly).
Perl 6 will be released officially this year. Obviously it won't have the success that Perl 5 had in its heyday. (cf my blog post for the 25th birthday of Perl itself: http://ebb.org/bkuhn/blog/2012/12/18/perl-cobol.html ).

The TIOBE index still gives Java at the top, followed by C, C++, C# and Python.
I don't know if they count Android programming as Java or if its popularity is only motivated by the fact that AFAIK it's still the default language inside big corporatey environments. Cobol is 21st :)
