command-line tool to sum the values in a column of a CSV file

I am looking for a command-line tool to calculate the sum of the values in a specified column of a CSV file. (**Update**: The CSV file might have quoted fields, so a simple solution just to break on a delimiter (',') does not work.) Given the following sample CSV file:

description A,description B,data 1, data 2
fruit,"banana,apple",3,17
veggie,cauliflower,7,18
animal,"fish,meat",9,22

I want to build the sum, for example, over the column data 1 with the result **19**. I have tried to use [csvkit] for this but didn't get very far. Are there other command-lien tools specialised in this CSV operation?
