It's because glob() uses the shell expansion, not regex. In the shell,
? means any character. You could use a regex filter:
my @files = grep { /^file\.[0-4]?[0-9]$/ } glob( 'file.[0-9]*' );

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
