I want to write a Perl script to sort a file containing multiple comma separated values (and output the results back to standard output)

scriptname -f n in_file

Switch Description
-f select field to sort by
where n = the nth value (in the csv) to sort by.

For example, here is what a in_file might look like...
1, abc, asldfjajfal
15, djsk, 1sljfal
24, aldfj, jfaldjfa

If I issue a 'scriptname -f 1 in_file, the output should be:
1, abc, asldfjajfal
15, djsk, 1sljfal
24, aldfj, jfaldjfa

If I issue a 'scriptname -f 3 in_file, the output should be:
1, abc, asldfjajfal
24, aldfj, jfaldjfa
15, djsk, 1sljfal

Anyone has any ideas? I am a complete Perl newbie stuck on a prctice example I created for myself.

Help!
