Linguist wrong warning about %n place markers

Have source string:

%1°%2′%3

and have translation string:

%3%1°%2′

This translation works fine at runtime. But Linguist 5.15.2 warns that "Translation does not refer to same place markers as in the source text". The warning goes away if you add a space after the %3, like this

%3 %1°%2′

But I don't want to have that space.
