$ifgreater(%_file_mod_datetime_raw%,1313807105,0,1) IS 1
Bad syntax.
Double apostrophes missing around the left part of the filter expression.
"$ifgreater(%_file_mod_datetime_raw%,1313807105,1,0)" IS 1
Should work.
%_file_mod_datetime_raw% GREATER %_file_create_datetime_raw%
Bad syntax.
Double apostrophes missing around the left part of the filter expression.
Maybe the right part of the filter expression's comparison operator GREATER needs to be a dedicated integer number, but no info field placeholder variable.
But this comparison, if it would work, will give no meaningful result, because modification datetime is always greater than creation datetime.
$if($greater(%_file_mod_datetime_raw%,%_file_create_datetime_raw%),1)
Bad syntax.
Double apostrophes missing around the expression.
A function named $greater does not exist.
Function $if missing parameters.
$ifgreater(%_file_mod_datetime%,%_datetime%)
Bad syntax.
Function $ifgreater missing parameters.
Please read the Mp3tag help manual.

If you want to detect any modification of a subject, then you need an indicator, which shows the difference between two states of the subject, for example ...
... the difference in the data content of the file.
... the difference in the checksum of the data content of the file.
... the difference in the access datetime stamp of the file in the filesystem.
... the difference in the modification datetime stamp of the file in the filesystem.
... or any useful combination of such indicators.
Mp3tag does not offer a pre-post state control tool for such revisions in the filter section of the list view.
There might be a way around.
When finished the work on a file, one can set an user defined tag-field e. g. 'DONE' to the value of '1'.
All files which contain this tag-field value DONE=1 can be suppressed in the list view by the filter expression ...
NOT DONE IS 1
To refresh the already filtered view press key [F3] twice.
After all work is done, the user defined tag-field DONE can be removed from all files.
There might be another way around without filtering (... already indicated in the referred thread in post #3).
When finished the work on a file, sort the file list view by %_file_mod_datetime_raw% (this needs to have a column defined) in order to move the latest modification to top or bottom of the list.
Leave this file there or ...
... select this file and delete it from the list by pressing key [Del].
To see all files again refesh the current view by pressing key [F5].
