Hello.
What is worth looking at in this one is the way the sorting options are used to produce the result.
By the way: I learned something else about Spotlight today: I have always found it a pain a certain place to have to reenter all the criterions each and every time I look for a piece of code. Today I opened the ~/Library/Saved Searches in order to look at some .SavedSearch in the PropertyListEditor, which are very handy to have in the Dock on a permanent basis. By accident I double clicked on the saved search in the SavedSearchFolder, and then I could change the original search argument while retaining all the added criterions for the search. 
Great labour saver for me, as I didn’t know about this.
I also learned about the benefits of relying on scptd files, as those files show up in quick look when I press space in a Finder window. (To be honest .scpt files with a creator code of “asDB” also do that, but those with ToyS don’t.
grep -v ":"ensures us that only entries for this year is returned.
grep -v " 0"removes files which are empty.
