If you assign a number to each volunteer and then make an array of total size of chunks and allocate every hour the number of the volunteer that should be able to give you the name of volunteer.

For example: 

$hash = { Ben = 5, scott => 4, jim => 1 };
@names = qw( Ben Scott Jim)
@array = [ 0,0,0,0,0,1,1,1,1,2];
$name = $names[$array[$_]];

You can create the @names and @array from the given data.
