UNIX for Beginners Questions & Answers

I have a csv file as shown below,

Code:

xop_thy		80	avr_njk		50	str_nyu		60
avr_irt		70	str_nhj		60	avr_ngt		50
str_tgt		80	xop_nmg		50	xop_nth		40
cyv_gty		40	cop_thl		40	vir_tyk		80
vir_plo		20	vir_thk		40	ijk_yuc		70		
cop_thy		70	ijk_yuc		80	irt_hgt		80

I need to align/sort the csv file based on the order mentioned in another file (keyword file) as shown below,

Code:

xop
avr
str
cyv
vir
cop
ijk
irt

The desired output is shown below,

Code:

xop_thy		80	xop_nmg		50	xop_nth		40
avr_irt		70	avr_njk		50	avr_ngt		50
str_tgt		80	str_nhj		60	str_nyu		60
cyv_gty		40		
vir_plo		20	vir_thk		40	vir_tyk		80		
cop_thy		70	cop_thl		40	
			ijk_yuc		80	ijk_yuc		70
						irt_hgt		80

The major condition is the column to be arranged pair wise (while rearrangement the string column should take the concerned value column adjacent to it together) like wise the pairs of columns to be rearranged based on the keywords. Another problem the keyword is the starting letters of each column, the keyword file has only starting strings of the columns strings. each column pairs are having common keyword but after the underscore symbol it vary. Therefore, I do not know how to make code for it. If it number or alphabet based sorting I can use function. But here i could not use it due to the complexity of condition. I am not sure, Is it possible to do the same. if it possible please help me.
Thanks in advance.
