Well, it's complicated.

Each status has a priority. The higher priority wins. Don't forget
that even if you see a 'modified' status overlay, it doesn't mean that
the file contents have changed - maybe only the properties have
changed. Here too, the higher priority of the text and property status
wins.

The priorities are (first mentioned has highest priority):

'conflicted' overlay:
                obstructed
                conflicted

'modified' overlay:
                merged
                modified
                replaced

'deleted' overlay:
                deleted
                missing

'added' overlay:
                added

'normal' overlay:
                external/normal
                incomplete

'needs lock' overlay:
                normal (property set or file rights readonly)
'locked' overlay:
                normal (working copy owns the lock)

no icon overlay:
                ignored
                unversioned
                none

But it gets more complicated:
If TSVN discovers that there are other overlay handlers installed (it
scans the registry and counts them), it prevents the shell from
loading all its handlers so other handlers can be loaded.
if more than 12 handlers are installed, 'added' will be replaced with
'modified', and 'locked' with 'normal'.
