Not tested this but:

• Used i to indicate case insensitivity.
• AFAIK special chars don't need \ in character classes.
• Used x to allow for new lines in regex to aid readability.
• Used ? in .+ match to make it parsimonius.
• Used \d instead of 0-9, it means the same thing.

   $_[0] =~ m/([A-Z\d_/.,-]+)
               \s*\t*
               (.+?)
               \s*\t*
               ([\d.]+)
               \t*
               ([\d.]+)*/ix;
