This is not an AGI, this is an AMI :)

AGI is a protocol where Asterisk creates a process and sends it the "AGI 
environment" (all the "AGI Tx >> agi_xxx" cruft above") and then waits for 
your process to issue requests and read responses. This "request, 
response" is repeated as your process completes it's tasks and exits.

Are you expecting your script to execute within the "context" of a channel 
within Asterisk or as a process external to Asterisk?

I read your original request:

as "I call in, I execute an AGI that looks up an extension based on some 
criteria, I want to dial that extension."

If this is close, the AGI should set a channel variable with the value of 
the extension and exit. Your dialplan would look something like:

 	exten = my-did,1,		verbose(${EXTEN}@${CONTEXT})
 	exten = my-did,n,		agi(lookup-extension)
 	exten = my-did,n,		dial{${LOOKED-UP-EXTENSION})
 	exten = my-did,n,		hangup()
