As long as the target is a parenthesized list of integers, this will grab the list:

Update: Fixed the regex to capture correctly by putting parens around the list inside the literal parens, and ignoring captures on the internal group.

# First, just grab the list
if (my ($list) = $line =~ /\((\d+(?:,\d+)*)\)/) {
    # split the list by commas, assuming no whitespace
    my @list = split ',', $list;
    # initialise the magic alpha incrementer key
    my $key = 'a';
    my %hash;
    for my $value (@list) {
        next unless $value;
        $hash{$key} = $value;
        # increment magically
        ++$key;
    }
    do_something_with(%hash);
}

Then the question is whether you need to do something with %hash for each line, or accumulate these across the whole file. If it's file level, move the my %hash; to before the if, and the do_something_with(%hash) after the if block.

Also, do_something_with(%hash) might be better as a hash reference:

do_something_with(\%hash);
