Accessing Sharepoint UserProfile Properties with Powershell script

Question

The following script spits out all UserProfile properties for users on Sharepoint 2007:

[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Server")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Server.UserProfiles")
# Function:          Get-UserProfiles
# Description:       return a UserProfileManager object containing all user profiles
# Parameters:        SSPName          SSPName    
#
Function global:Get-UserProfiles($SSPName)
{
    $ServerContext = [Microsoft.Office.Server.ServerContext]::GetContext($SSPName);
    $UPManager = new-object Microsoft.Office.Server.UserProfiles.UserProfileManager($ServerContext);
    return $UPManager.GetEnumerator();
}

$profiles = Get-UserProfiles("SharedServices");
$profiles | ForEach-Object { $_.GetEnumerator();}

However, what I want to do is be able to return a table, or csv file of specific values in the profile, e.g. Username, WorkEmail, WorkPhone. I have tried piping the output to |ft Username, WorkEmail, Workphone and | select Username, WorkEmail, WorkPhone but this just returns blanks.

I feel like I am so close. I don't want to replace the $_.GetEnumerator() call with lots of $_.Item("property") calls and it doesn't feel like I should have to. Any ideas?
