Code:
[ctsgnb@shell ~/sand]$ cat f1
K2_34625-34675
K7_988963-988983
K12_773882-7734102
[ctsgnb@shell ~/sand]$ cat f2
U_P_321_9_3_11.ab1
U_P_322_9_3_11.ab1
U_P_323_9_3_11.ab1
[ctsgnb@shell ~/sand]$ paste f2 f1 | while read a b
> do
> t=${b##*_???}
> v=$(echo $b | sed 's/.*_...//;s/-.../-/')
> n=${b%$t}$(( -($v) )).${a#*.}
> echo "mv $a $n"
> done
mv U_P_321_9_3_11.ab1 K2_34650.ab1
mv U_P_322_9_3_11.ab1 K7_98820.ab1
mv U_P_323_9_3_11.ab1 K12_7733220.ab1
[ctsgnb@shell ~/sand]$

If it does what you want then just change the echo "mv $a $n" with mv "$a $n"

please give more clue about the caculation for the renaming :

34625-34675 = -50
and what should be calculated in the
773882-7734102
????

I assumed you want to keep the first 3 number unchanged so that is becomes:
-(882-4102)=3220
so the new name will be K12_7733220.ab1
by the way, i also assume you have the same number of entries in your both set of files

rename

rename(1T)						       Tcl Built-In Commands							rename(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       rename - Rename or delete a command

SYNOPSIS

       rename oldName newName
_________________________________________________________________

DESCRIPTION

       Rename the command that used to be called oldName so that it is now called newName.  If newName is an empty string then oldName is deleted.
       oldName and newName may include namespace qualifiers (names of containing namespaces).  If a command is renamed into a different namespace,
       future invocations of it will execute in the new namespace.  The rename command returns an empty string as result.

EXAMPLE

       The  rename command can be used to wrap the standard Tcl commands with your own monitoring machinery.  For example, you might wish to count
       how often the source command is called:
	      rename ::source ::theRealSource
	      set sourceCount 0
	      proc ::source args {
		  global sourceCount
		  puts "called source for the [incr sourceCount]'th time"
		  uplevel 1 ::theRealSource $args
	      }

SEE ALSO

       namespace(1T), proc(1T)

KEYWORDS

       command, delete, namespace, rename
