Then use Stefans <available>s in a <condition>
<condition property="version" value="1.7.0"><available-17>
<condition property="version" value="1.6.3"><available-163>
...
Since Ant 1.7.1 you could use <antversion>
<project>
<antversion property="v"/>
<echo>Version: ${v}</echo>
</project>
So maybe you want to use that task and port that to your environment.
