Yes. This issue has nothing to do with paragraph direction (and the Gnus summary buffer ought to set bidi-paragraph-direction to left-to-right anyway). This issue is about reordering a line of text that is not really a contiguous text, but rather a series of separate fields. Either each field needs to be reordered separately, which can be done by separating them with TABs, or we need to "fix" the default reordering (which assumes the whole line is a single piece of text) by inserting LRM characters in strategical places.
