reporting plugin: sorting contents by modification date - is this the correct syntax?

Question

I am using the reporting plug-in macros to generate a list of child pages along with their modification dates. I want the reporter to do the sorting. Can anyone suggest any mistakes in this syntax?

{report-table}

@{content-reporter:space=@self|types=+page|scope=@self > descendents} 
{text-sort:content:modification date|order=descending} 
{content-reporter}

{report-column:title=Title}{report-info:page:title|link=true}{report-column} 
{report-column:title=Last Modified}{report-info:page:modification date}{report-column}

{report-table}

Here are the results I see (note the sorting does not happen)

The answer is: use date-sort instead of text-sort for date fields.

{report-table}

@{content-reporter:space=@self|types=+page|scope=@self > descendents}

{date-sort:content:modification date|order=descending}

{content-reporter}

{report-column:title=Title}{report-info:page:title|link=true}{report-column}

{report-column:title=Last Modified}{report-info:page:modification date}{report-column}

{report-table}
