Strangly only the base file and the meta (.svn) data get updated but the "real" working copy file remains unchanged, rendering this file "locally modified".

Nope ...

Sure, could be; but Subversion doesn't insert the UDS<> stuff. That part
must be coming from PushOK.

I'm just guessing, but it looks like they use that as a session
identifier; and the "project root folder" is not being "replaced"; this
looks like a session ID plus relative path /within/ the working copy.

It has nothing whatsoever to do with Subvesion. Your guess about what it
means is as good as mine ...

[insert blurb here about not using proprietary tools]

If you're not actually constrained to MSSCCI but can use VAPI instead,
you could try using AnhkSVN.
