That's a great news !
Yes, Tor is a solid choice : ZCash for instance also chose it, and is funding a rust implementation named 'Arti', which is quite exciting (Let's just hope that it won't have the same ending as Kovri...)

I have a question regarding the implementation : will the use of Tor Hidden Services be enforced by default ? I personally hope so, as privacy should always be the default (or there isn't any privacy at all). And in the specific case of Tor, it eliminates the risk of malicious exit nodes (as Hidden Services don't use them), which also matters in terms of security : https://www.researchgate.net/publication/305053676_Bitcoin_over_Tor_isn%27t_a_Good_Idea (not 100% applicable to Zano, just an example of what type of attacks could be used).
