Do you want to have incremental build numbers (without gaps), or just
a reliable way of identifying the source code revision that was used
for the build?

If there is no requirement for consecutive numbers, you can use the
highest revision number in the working copy as a basis (svn up will
tell you this and there are other tools that can assist you with this:
SubWCRev on windows for example -- delivered with TSVN).

By starting your build with a step that retrieves the highest SVN
revision number and stores it in a (non-versioned) include file which
is used by the subsequent build steps you will get a build that can be
related back to the source version.

One thing to take notice of is that there could be local modifications
present in the workong copy that is being used to build the project.
svn status can show you this.
