Three other examples from Power Klingon of
-jaj with the subject not following the verb:
May the Klingon Empire continue forever.
reH tlhIngan wo' taHjaj.
may the spirit of Kahless live within you.
SoHDaq qeylIS qa' yInjaj.
May the bile of the vanquished fill your hands.
jagh lucharghlu'ta'bogh HuH ghopDuŽlIj lungaSjaj.I wrote down these texts from the audio so I might be mistaken here and there. If anyone knows better, please correct me.
In the last example the OVS order would be:
jagh lucharghlu'ta'bogh HuH lungaSjaj ghopDuŽlIj .which is quite complicated because the object is a verbal expression:
The slime
HuH of the enemy
jagh that someone finished slaying
lucharghlu'ta'boghAnyway, this shows that the word order is: OSV
-jaj if there is an object, which need not be the case as in the first two examples.
Not unreasonable that in certain circumstances certain grammatical rules apply. In English the "toast"-sentence starts with
May and in Klingon it ends with
-jaj so there is some similarity.
I modified this because I accidentally swapped subject and object: hands contain slime 
I
