Here's a (slightly trimmed) script I use to control Winamp: 
#!c:/perl/bin/perl -w
use strict;
use Win32::API;

use constant WM_USER        => 1024;
use constant WM_COMMAND        => 273;

my %commands = (
    PREV                                => 40044,
    NEXT                                => 40048,
    PLAY                                => 40045,
    PAUSE                                => 40046,
    STOP                                => 40047,
    # Lots of other commands trimmed for space...
);

my $cmd = uc shift;
if (exists $commands{$cmd}){
    my $FindWindow = new Win32::API(
        'user32', 
        'FindWindow', 
        ['P', 'N'], 
        'I'
    );

    my $SendMessage = new Win32::API(
        'user32', 
        'SendMessage', 
        ['I', 'I', 'I', 'I'], 
        'I'
    );

    my $hwndWinamp = $FindWindow->Call('Winamp v1.x', 0);

    $SendMessage->Call(
        $hwndWinamp, 
        WM_COMMAND, 
        $commands{$cmd}, 
        0
    ) if $hwndWinamp;
} else {
    print "Invalid command.\n";
}

The most useful Winamp related script I have is the one that locks my computer and pauses Winamp. This snippet checks to see if Winamp is currently playing, and if so sends a "pause" command: 
if ($hwndWinamp){
    if ($SendMessage->Call($hwndWinamp,WM_USER,0,104) == 1) {
        $SendMessage->Call($hwndWinamp,WM_COMMAND,40046,0);
    }
}
