I vaguely remember there to be a perl module interface available for
such queries. That might be the "best way" from perl. I don't know
it though so will tell you what I would do.

On the command line I would do:
$ apt-cache policy xterm
xterm:
Installed: 312-1
Candidate: 312-1
Version table:
*** 312-1 0
500 http://ftp.us.debian.org/debian/ sid/main amd64 Packages
500 http://ftp.us.debian.org/debian/ testing/main amd64 Packages
100 /var/lib/dpkg/status
That shows my Sid system as having only one version available in all
three locations of installed (100 /var/lib/dpkg/status), in the
Testing repository, and in the Sid unstable repository. The "***"
indicator points to the currently installed version. If the installed
version were different then it would point to a newer version
available.
Alternatively there is apt-show-versions.
$ apt-show-versions xterm
xterm:amd64/testing 312-1 uptodate
If there were a newer version available it would show "upgradeable 312-1"
or some such newer version number instead of "uptodate".

See the above for two different ways to get the newer version number.
