Okay, so you have created a useless script. This is one of the pitfalls lacking good requirements planning.
As you now know, there is no way to encourage scripts to run on a specified interval. Nor is there an event-model in Airtable that might recognize when a script should fire. I believe both of these are likely features in Airtable’s future, but until then your options are limited.
Write the script block in a way that causes it to always run looking for the linking conditions to process. This involves a while(true) loop that never evaluates to false. There are two key issues with this - (a) Airtable might not like it; it’s using server resources day and night, and (b) it requires your browser to be live and uninterrupted to run the block 24/7.
Move the script to a proper API-driven approach that fires every ten minutes.
