Give it a larger pen-up (negative-value) gap between the symbol and the text element, to push the nominal "location" of the text farther along by about half the text width, and then include a negative-X component (like the negative-Y one) in the text specification, to "back off" the start of the text so the nominal location is in the middle of it.  You'll have to experiment with the exact numerical values to fine-tune it, as the result is affected by the size and font and content of the text.

 

Here's an example of a quickie I threw together using a symbol I already had, that illustrates reverse direction with text nicely positioned in the gap between the symbol and the subsequent line [pen-down] element.  The "base" linetype definition is shown in the right side, which is a Line drawn from left to right, with the symbol pointing up.  The left side is a Line drawn from right to left, and the text is uprighted but still positioned in the same relationship to the symbol and the line element.

 

EDIT:  To be more specific, take half the gap after the text and add it to the gap before the text, and back the text off by the same amount.  Rounding off your values for those gaps to 38 and 52, try something like this, the half-value being 26:
