That script looks to be written in a quite old style of Perl, and it doesn't make use of any standard modules where it could, and could take a lot of clean up work to bring it up to modern standards. Sure, it could be modified*, but it might not hurt to take a step back:

The goal is to avoid using switches when invoking /usr/bin/vncserver

Are you sure that's the easiest solution to the problem (which you haven't described)? It requires you to maintain a patched version of a script you don't fully understand. Why not just write a small wrapper shell script around vncserver?

#!/bin/sh
/usr/bin/vncserver -geometry 2000x1200 # ... etc

* Quick & dirty example (requires Config::Tiny):

use Config::Tiny;
my $cfg = Config::Tiny->read("$ENV{HOME}/.vnc/config");
$geometry = $cfg->{_}{geometry} if exists $cfg->{_}{geometry};

Just enough rope ;)
