If you're OK with an asynchronous response, I've come up with a workaround. Trigger a logicblock to send the data to a webhook. You're not really looking up the data, but you can pass it to some other applet for usage, which is pretty much the same thing in many cases. I've sent data to phone notifications, for example.
IF <Your real condition>
THEN: Webhook: Somehow trigger a logicblock. (In my case I'm changing a variable, but directly calling it should work too.)
If or else (or both): Call <IntermediaryWebhook>. Pass the data you want in the three Value fields under advanced options
IF <IntermediaryWebhook>, which will be receiving 0-3 values
THEN: <Your real action, which can now use those values>
Sending to a script would be harder but I bet you could still do it if Have the data get written to something the script can look up (an email or google doc spreadsheet perhaps?). Delays would be a bit tricky as this is still asynchronous though.
