I've tried your code but it required a small change to run for me under perl v5.20.3. As it stands, the -t causes it grief:

[11541] START [02@21:54:27] Warning: Use of "-t" without parentheses i
+s ambiguous at ./sigs.pl line 61.
[11541] START [02@21:54:27] Use of ?PATTERN? without explicit operator
+ is deprecated at ./sigs.pl line 61.
[11541] START [02@21:54:27] Search pattern not terminated or ternary o
+perator parsed as search pattern at ./sigs.pl line 61. Leaving...

So changing line 61 to be this:

logger(INFO, sprintf("We %s connected to a TTY", -t () ? 'ARE' : 'ARE 
+NOT'));

[download]

It then runs and appears to handle the TSTP and subsequent CONT perfectly well. Which version of perl are you running and on which OS?
