Numeric Sorting in script and non-script columns

Based on what Column - Custom Text and Regexp does:

function OnInit(initData)
{
    // DON'T add columns here.
}

function OnAddColumns(addColData)
{
    // Add columns here.
}

function OnScriptConfigChange(configChangeData)
{
	Script.InitColumns;
}

I'd expect the call to be Script.InitColumns(); with the brackets, but it probably works whether or not they are used, due to a quirk of how ActiveScripting methods/properties are implemented. The example script I linked didn't use them, so I left it that way, but I'd add them in unless it causes problems.
