AppleScript - Evernote - Tag Variables

The import with Hazel and AppleScript in Evernote works fine.
Now I want that Hazel reads an OCRed document, find the company name and give this name in a AppleScript variable for a Tag in Evernote in this way
create note from file theFile notebook „Tax-2017" tags {„Billing", companyName}
Which lines must I integrate in the script to read out the content for the variable "companyName"?
Thank you for hints!
