Haml Integer values in select options

[Google Code Exporter]

1. Parse the following with HamlParser (no options used) :

%select
    %option{:value => '0'} Transport
    %option{:value => '1'} Manufacturing
    %option{:value => '2'} Logistics
    %option{:value => '3'} Supplying

Expected output is a select element containing options whose values are 
Integers. Instead, following messages are displayed and rendering is broken :

Notice: Undefined offset: 7 in src/includes/PHamlP_3.2/haml/HamlParser.php on 
line 959

Notice: Undefined offset: 7 in src/includes/PHamlP_3.2/haml/HamlParser.php on 
line 966

It seems that '0' and '1' are not correctly interpreted (Boolean instead ?). 
Other values such as '2', or '10' are fine. However, I'm not sure how to fix it 
properly right now, or if that behaviour is intended (which I seriously doubt).

I'm using PhamlP 3.2 with PHP 5.4.10 on Arch Linux, default setup.

I forgot this report, but it works fine with double quotes, though "0" still 
doesn't.
