print "$list$a$b "; prints only first file and nothing else

I don't know if you are aware of it, but one obscure rule in Perl is do not use $a and $b as variables, because they interfere with Perl's sort function. I don't think it's a problem here, but it could be that sort is invoked internally, and your $a and $b are getting messed up. Try changing those variable names.
