it seems, that this issue is caused by comma as separator in script metadata fields Tags and/or ExternalModuleDependencies. After removing commas, tags were published correctly (but tag PSScript was no more added).

[peetrike]

hm, same effect occurred when script file did not have metadata field Tags

[peetrike]

the same effect occurs, when there is Tags field but no required modules are found from script. Like, for example, in #1248
