This is deliberately forbidden by standard. See RFC 2181, Section 5.2 ("TTLs of RRs in an RRSet")
Why would you want to do this?

Subject: Configuring different TTLs in multiple RRs for the same domain name, TYPE, and CLASS
Greetings.
Is it possible in BIND to configure multiple resource records for the same domain name, TYPE, and CLASS with different TTL values? For example:
Test-txt.example.com 300 IN TXT "Test 300"
Test-txt.example.com 400 IN TXT "Test 400"
Test-txt.example.com 500 IN TXT "Test 500"
Test-txt.example.com 600 IN TXT "Test 600"
Test-txt.example.com 700 IN TXT "Test 700"
I tried it, and BIND set the TTL for all five records to 300 (or more specifically, the TTL of the first one of the RRs in the file). I looked for a BIND directive in the manual to change this behavior but could find no obvious candidate.
Thanks,
