The tags are in the /tags directory only if you place them there. For
subversion, tags, branches, trunk -- everthing is a versioned tree. Tag is
just a human-friendly name given to the tree by the users. There is no way
to tell introspecting the repository if a versioned tree is a tag.
Let us say you do have /tags directory where you keep the tags. Let us also
assume that you don't change the tag once you created it. Lot of people just
use script friendly names for the tags so that it is easy to determine which
tag is the recent (suffix it with date and time, for example). If not, you
can do "svn log --limit 2 -v -q $REPOURL/tags" and you should get two most
recent tags (the first log corresponding to the latest and the next will be
latest - 1). You will have to write a simple bash / perl script to parse out
the tag name from the log output.

Same bash / perl script that parses out the tag name (above) can parse the
revision as well. [something similar to Andrew's example should work].
