You need to Format Paint the words within tags. Just type the text the way you want it to be, i.e. in the correct word order. Afterwards you need to click on the brush icon in the toolbar. Highlight the word within tags in the source segment and then the corresponding word in the target segment. Depending on your settings you might need to press Enter to move the tags. (You can change this under Tools > Options > Format Paint > Press Enter to confirm format paste.)
I personally prefer not to display tags but Format Painting colors because that's easier on my eyes. (To do so go to View > Tags > Colours (Standard volour formatting)).
