Here you can probably even see how it was drawn:

   

If you look at the gaps (red arrows), it seems likely that this glyph was not drawn in one stroke. Instead, two letters have merged into one another. Its could be a typical ‘t’ (see also the t directly to its left) and the "3" similar variants of a z. In one place, the ‘z’ has been written over the horizontal bar of the t.

This also supports the theory that it is tz, in addition to all the other words that make sense with tz. Especially since he apparently comes from the language area where this harder pronunciation was common.
