Using this code:

require 'rubygems'
require 'win32/taskscheduler'

t = Win32::TaskScheduler.new("task", {
   "start_month"  => 4,
   "start_day"    => 11,
   "start_hour"   => 7,
   "start_minute"	 => 14,
   "trigger_type"	 => Win32::TaskScheduler::DAILY,
   "type"         => { "days_interval" => 2 }
})

t.application_name = "ruby test.rb"
t.save

Which is taken almost verbatim out of:

http://jp.rubyist.net/magazine/?0005-RLR-en

It saves C:\Windows\Tasks\task.job but upon viewing the scheduled tasks list, it does not appear.

I'm not really a windows maven, but here's what I know about the environment:

Windows 2003 Server R2
Ruby mingw32 build of 1.8.6 pl 114 (2008-03-03)

gem list --local reports these gems in use:

win32-api 1.4.3
windows-api 0.3.0
windows-pr 1.0.5
win32-taskscheduler 0.2.0

HTH, Let me know if you require any more information.

Thanks as always,

Is start_year the only required field? My memory is failing.

We'll add required fields to the next release Erik. Thanks for
the report.

I'll give this a shot, but if I can be granted license to
complain a little, the distinct lack of required fields
checking and documentation has made this library very hard
to work with. If I knew more of what I was doing on windows
I'd gladly contribute patches but I don't think that would
serve you well with my current level of knowledge.

Is there any chance that this lack of information can be
remedied in the next release?

It's not a bug. 
You have ommitted required field 'start_year'. 
The code should be like this:
t = Win32::TaskScheduler.new("task", {
   "start_year"  => 2010,
   "start_month"  => 4,
   "start_day"    => 11,
   "start_hour"   => 7,
   "start_minute"	 => 14,
   "trigger_type"	 => Win32::TaskScheduler::DAILY,
   "type"         => { "days_interval"
=> 2 }
})

Of course, the missing field checking routine might be helpful.
