Well, There is another solution which I have been using for a while. If you are using Zotero for your reference management (if you don't I strongly recommend to do so), there is a plugin which downloads the number of citation from google scholar:

1. install Zotero
2. go to this GitHub Repo and download the plugin and install it as instructed
3. on you Zotero app add the "extra" to the fields:

now you have the number of citations right into your refrence managment software and you can sort your collections accordingly. If you use the pluging to download citations for many items at once, Google will ask you for captcha.
