You may find it easier to split on the comma: 

my @data = split /,/;

# How do you validate your data? Do you need to?
warn "bad line", next if @data != 15; # or something...
my @not_numeric = grep { length $_ == 0 || /[^-\d\.]/ } @data[2..$#dat
+a];
warn "fields contain non-numeric data: @not_numeric", next if @not_num
+eric;

(There are better ways to check if something is numeric, this was just quick'n'dirty since I don't know your real requirements.)

Or, if you want to go the CPAN route, Text::CSV::Simple and several other modules exist.
