Sort by function

how eliminate second get-minvalue?

gci | sort {get-minvalue ($_.creationtime, $_.lastaccesstime, $_.lastwritetime)}, name | ft name, @{label="mindate";expression={get-minvalue ($_.creationtime, $_.lastaccesstime, $_.lastwritetime)}}

i'd have like

gci | sort {mindate=get-minvalue ($_.creationtime, $_.lastaccesstime, $_.lastwritetime)}, name | ft name, mindate

is trying do?

gci |  	select @{n='minvalue';e={ (($_.creationtime, $_.lastaccesstime, $_.lastwritetime)|measure-object -min).minimum }}, name
