As a prelude, if you think that there is [ts'] anywhere in Georgia, you should provide a recording of unmodified [ts'] for comparison, especially an intervocalic one. Shosted & Chikovani provide airflow and acoustic evidence in initial position for a closure before the fricative in Georgian – that dialect.
The tokens that you provide are comparable to supposedly ejective /(t)s'/ in Tigrinya, based on my own work with an Eritrean speaker, where there is often no closure before the fricative. You should also look at this article on Tigrinya phonetics, which draws on other (younger) speakers from roughly the same area of Eritrea. There is no closure before the fricative release, as found in the Shosted and Rose data (same Shosted, different language). It is important to note that there is no contrast in Tigrinya between /ts'/ and /s'/, and that the sound is traditionally said to be /s'/ but could just as well be called /ts'/. I would say that the evidence you give suggests [s'] and not [ts'].
